August 1 is the date this class has been building toward. It's the first day college programs can open direct contact with the 2010s, and for a group that has already been through two USA Hockey national camps, a USHL Phase I draft, and a QMJHL draft, the file on most of these players is already thick.

This is the blue line. Fifteen Massachusetts defensemen, ranked on what they actually did rather than what they might become — 2025-26 prep production, two years of national camp results, and where they landed in the USHL and QMJHL drafts. Forwards get their own board later this week.

One number frames everything below it. Six Massachusetts defensemen went to the USA Hockey National 15 Camp in 2025. Six went to the National 16 Camp in 2026. Only three of them are the same players. Cotter, Anderson, and Ware went twice. Fishbone, Poti, and Porter climbed in. Martin, Guo, and Shaun Farrell — who played MIAA hockey at Catholic Memorial last season and so isn't eligible for this prep board — didn't get the callback. Half the group turned over in twelve months, which is the best argument there is against reading any of this as settled.

How this is built. Every player here is a 2010-born Massachusetts defenseman who played a 2025-26 prep varsity season. Incoming players with no prep record are not eligible for this board — they'll be ranked once they've played. The order weights five things: 2025-26 prep production, the National 15 Camp in 2025, the National 16 Camp in 2026, USHL Phase I draft standing, and QMJHL draft standing. The most recent camp invite carries the most weight, junior draft standing next, prep points last — because defensemen get undersold by a box score, and because the scouts who spent a week watching these kids saw more than a scoresheet does.

One more column is coming. Starting August 1, we'll add a College column to the right side of this board and fill it in as commitments are announced. The board stays live through the season — same fifteen names, same credentials, with the destination filled in one at a time. That's the whole point of publishing it now: it's the baseline before anybody signs.

The Fifteen

In board order — where each player stands, what backs it up, and what the numbers don't say.

Minutemen Flames · St. Sebastian's
Prep 6-23—29Nat 16 Camp 3USHL Sioux FallsQMJHL Halifax

Twenty-nine points is the highest total any 2010 defenseman put up in prep hockey last season, and he's one of the few who actually scored — six goals alongside 23 assists. He wasn't invited to the National 15 Camp at all in 2025. A year later he was at the 16 camp with three points and had both Sioux Falls and Halifax take him. There is nothing left on the checklist for him to collect.

Neponset Valley River Rats · Belmont Hill
Prep 0-25—25Nat 15 CampNat 16 CampUSHL OmahaQMJHL Cape Breton

Twenty-five assists as a freshman, running the Belmont Hill power play. That is the most assists any 2010 defenseman recorded in Massachusetts prep hockey last season, and he did it in his first year against juniors and seniors. Quarterbacking a NEPSAC power play at fifteen is a job most programs don't hand to an underclassman, and Ware held it all year. Omaha took him in the USHL and Cape Breton took him in the Q. The goal column reads zero, which is the one thing left to add — but distribution at that volume, that early, is the harder skill and the one that carries.

Green Bay Gamblers (USHL)
Prep 5-17—22Nat 15 Camp 4Nat 16 Camp 2USHL Green Bay — confirmedQMJHL Newfoundland

The most dynamic offensive defenseman in the 2010 Massachusetts class, and it isn't especially close. Five goals and 17 assists at St. Mark's — the only defenseman in the group who both scores and distributes at volume. He was the top-scoring Massachusetts 2010 defenseman at the National 15 Camp with four points, then went back to the National 16 Camp and produced again. Two straight summers in front of national evaluators, two straight summers on the scoresheet. He's confirmed to Green Bay in the USHL, which makes him the first player on this board with his next stop settled. Newfoundland holds his Q rights. He jumps a level this fall while most of this list plays another prep season, and that is the fastest track available to a defenseman his age.

Islanders Hockey Club · Winchendon
Prep 1-16—17Nat 16 Camp 2Camp All-Star GameUSHL Cedar RapidsQMJHL Rouyn-Noranda

The cleanest riser on the board, and the most intriguing projection in the class. No National 15 Camp invite in 2025. Seventeen points at Winchendon, then a National 16 Camp invite — and once he got there he was named to the camp all-star game, which is the part that matters. Being invited is one thing; being one of the best players in the building that week is another. Cedar Rapids and Rouyn-Noranda both drafted him. He also has the frame college and junior staffs project on, which at this age is a real separator on a blue line where most of the group is still filling out. The pedigree is there too — his father, Tom Poti, played more than 800 NHL games. A year ago he was outside the USA Hockey process entirely. He is now one of the more valuable pieces in it.

Minutemen Flames · Master's Academy International
Prep 3-9—12Nat 15 Camp 3Nat 16 Camp 5USHL DubuqueQMJHL Saint John

The best two-year camp arc of anyone here. Three goals and no assists at the 15 camp; two goals and three assists at the 16, leading all Massachusetts defensemen there. He went from a shooter to a player who makes the players around him better inside twelve months. He leaves Cushing for Master's Academy International this fall, the one meaningful program change in the top fifteen. If this board were built on camp weeks alone he'd be at the top of it.

Minutemen Flames · Dexter Southfield
Prep 2-9—11Nat 16 Camp 2USHL Sioux FallsQMJHL Drummondville

Same path as Poti — no 15 camp, 11 points at Dexter, then the 16 camp invite with two points and rights taken by Sioux Falls and Drummondville. Two of the six 2026 camp defensemen came from outside the previous year's group, and Porter is the second of them. He closes out the sweep: every 16 camp invitee was drafted twice.

Neponset Valley River Rats · St. Sebastian's
Prep 2-11—13Nat 15 Camp 1USHL Sioux FallsQMJHL Rimouski

The strongest case on this board that a ranking is too low. Thirteen prep points is more than three of the six players in the 16 camp group. He was at the 15 camp, didn't get the callback, and it didn't cost him anything with the junior clubs — Sioux Falls and Rimouski both took him anyway. When USA Hockey and the drafts disagree, this is what it looks like.

Minutemen Flames · Belmont Hill
Prep 2-8—10Nat 15 Camp 0QMJHL Shawinigan

Ten points at Belmont Hill, pointless at the National 15 Camp, no callback in 2026, and Shawinigan took him in the Q with no USHL club following. A half-credential profile: enough for one league to commit a pick, not enough for the other. He's the second Belmont Hill defenseman in this top ten, which says something about that program's blue line.

Minutemen Flames · Rivers
Prep 2-1—3QMJHL Drummondville

The hardest player on this board to place. Three points at Rivers, no invitation to either national camp, and Drummondville drafted him regardless. Someone in the Q organization saw something that no camp roster and no box score reflects. He ranks ninth on the strength of that pick alone, and he's the most likely name here to look badly ranked in either direction by March.

Cape Cod Whalers · Milton Academy
Prep 0-3—3Boys Festival

Three points at Milton and a Boys Festival invitation this spring that he didn't convert into a Final 40 spot. Modest production, but he's the last player on this list with any 2026 USA Hockey credential at all, which is the line that separates him from everything below.

Boston Americans · BB&N
Prep 0-8—8

The name college staffs should be writing down. Eight points at BB&N with no camp invitation, no festival, and no draft selection — more production than four of the players ranked above him. Everything about his ranking is a function of what he hasn't been given rather than what he's done. If any player on this board moves up sharply by March, the odds favor him.

Islanders Hockey Club · Roxbury Latin
Prep 3-4—7

Three goals from the blue line is tied for the third-most in the entire 2010 defense class, behind only Fishbone and Cotter. Seven points overall at Roxbury Latin. He shoots more than almost anyone here, which is a real trait at this age, and he has no national or junior credential attached to it yet.

Militia Hockey Club · Nobles
Prep 1-5—6

Six points at Nobles with no camp or draft attachment. A steady defensive season in one of the stronger NEPSAC programs, which is worth more in a coach's evaluation than it is in a points column. He needs a scoring jump this winter to move on this board.

South Shore Kings · Brooks
Prep 0-2—2

Two points at Brooks, no credentials. He makes the fifteen because he played a full prep varsity season in this class, and the sophomore year is where players in his position separate. This is the spot on the board that turns over first.

Cape Cod Whalers · Thayer Academy
Prep 0-0—0Thayer Varsity as a Freshman

The point total is the least interesting thing about him. Vernazza made the Thayer Academy varsity roster as a freshman, which in a program of that caliber is a genuinely hard thing to do — most players in this birth year spent last season on a JV bench or waiting a year for the spot. He won it in year one. Zero points reflects the minutes a freshman defenseman gets on a deep NEPSAC blue line, not the player.

The traits are the reason he's on this board. Like Poti, he brings real size and length to the position, and he pairs it with the best hockey sense of anyone in the back half of this ranking — he reads plays a step early and defends with his stick and his gaps rather than chasing. That's the profile that scales when the ice time comes, and the ice time should come this year with a season of varsity behind him. He also leaves Militia for the Cape Cod Whalers on the club side.

Nobody on this list has more room to move than he does.

Six at the 15 camp, six at the 16 camp, only three at both. Whatever a camp invite is worth to a college staff, it plainly isn't a permanent grade — and that cuts both ways for everyone sitting outside the top six right now.

What Happens Next

The thing to watch isn't who commits first. It's whether college programs weigh the camp invite the way the junior clubs did — and given that half the invite list turned over between 2025 and 2026, they'd be reasonable not to. Six of these players hold every credential available. Three more hold junior rights without the 2026 callback. If the commitments track the top of this board, the pipeline is working as advertised. If they don't — if a Martin or a Tang goes early to a program that watched him play rather than reading his resume — that's the more interesting story.

Forwards are up next. Same format, same criteria, same College column waiting to be filled.
