The 11-3 William & Mary Tribe roll into TD Arena as slim road underdogs against the Charleston Cougars. Bryan Bash breaks down why the Tribe’s #44 ranked adjusted defensive efficiency makes them a prime candidate for an ATS pick in this conference showdown.
The Setup: William & Mary at Charleston
Charleston’s laying 2.5 points at home against William & Mary on Monday night, and at first glance, this looks like your standard mid-major CAA toss-up. But here’s the thing – when you dig into the collegebasketballdata.com efficiency numbers, this line is essentially saying these teams are dead even on a neutral court. That’s where I have a problem.
William & Mary rolls into TD Arena at 8-3 with an adjusted net efficiency of +10.8, good for 67th nationally. Charleston sits at 4-5 with a -5.1 adjusted net rating, ranking 240th in the country. That’s a 16-point gap in efficiency differential, and the home team is only getting 2.5 points? The Cougars are riding a five-game winning streak, sure, but let me walk you through why that’s masking some serious structural problems.
This game lives and dies on tempo control and shooting efficiency – two areas where the Tribe hold massive advantages. Charleston’s trying to slow this down and grind, but William & Mary’s pace-and-space attack is built to break that style.

Why This Number Makes Sense (or Doesn’t)
Here’s why this line makes sense from the book’s perspective – Charleston’s won five straight and they’re at home. The public sees that streak and assumes momentum matters more than fundamentals. But the efficiency data from collegebasketballdata.com tells a completely different story.
William & Mary’s adjusted offensive efficiency sits at 111.3 (111th nationally), while their adjusted defensive efficiency ranks 44th in the country at 100.5. That defensive number is elite for this level. Charleston? They’re at 108.3 offensively (165th) and 113.4 defensively (293rd). That’s not just a gap – it’s a chasm on the defensive end.
The Tribe are allowing just 97.3 points per 100 possessions in raw defensive rating, ranking 53rd nationally. Charleston’s giving up 110.0 points per 100 possessions, ranking 246th. Do that math over 70-75 possessions, and you’re looking at a 9-10 point swing just from defensive efficiency alone.
But here’s where it gets really interesting – the pace battle. William & Mary plays at the 6th-fastest tempo in college basketball at 77.0 possessions per game. Charleston? They’re crawling at 67.7 possessions (204th). The Tribe want to run, and Charleston wants to walk it up. Whoever controls that tempo wins this game, and W&M has the defensive pressure to force it.
William & Mary’s Situation
The Tribe are built around elite ball movement and defensive disruption. They rank 9th nationally in assists per game at 20.0, which tells you everything about their offensive philosophy – they share the rock and generate open looks. That 57.5% effective field goal percentage (36th nationally) isn’t an accident.
Defensively, this is where William & Mary separates itself. That 26.1% opponent three-point percentage ranks 9th in the nation – they absolutely smother shooters on the perimeter. They’re also generating 9.1 steals per game (47th), which fuels their transition attack. Those 198 fast break points aren’t just a number – they’re why this team wants to speed you up and break you down.
The balanced scoring attack features five guys in double figures, led by Kilian Brockhoff at 11.7 points per game. No one player dominates the ball, which makes them incredibly difficult to game-plan against. The main concern? They’re 350th in offensive rebounding percentage at just 24.4%, and they turn it over 14.9 times per game (337th). Against a team that takes care of the ball, those turnovers could be costly.
Charleston’s Situation
The Cougars’ five-game winning streak looks great on paper, but the underlying numbers are concerning. They’re shooting 26.1% from three-point range, ranking 363rd nationally. That’s brutal. Their 46.7% effective field goal percentage ranks 336th. They simply can’t score efficiently unless they’re getting to the rim or the free throw line.
The one area where Charleston excels? Ball security. They rank 3rd nationally in turnover ratio and commit just 9.1 turnovers per game (11th). Connor Hickman leads at 14.8 points per game, and they’ve got decent balance with four guys over 10 points. But when you’re shooting 41.4% from the field overall (323rd) and can’t make threes, you’re living on the margins.
Defensively, they’re allowing 44.5% from the field (232nd) and a concerning 36.8% from three-point range (324th). That perimeter defense is going to be a massive problem against a Tribe team that moves the ball as well as anyone in the CAA. The 32.4% offensive rebounding rate (133rd) is solid, but that won’t matter if they can’t get stops.
The Matchup: Where This Gets Decided
I keep coming back to those perimeter defense numbers because they’re just too extreme to ignore. William & Mary allows 26.1% from three (9th nationally). Charleston allows 36.8% from three (324th). The Tribe defend the arc like their lives depend on it, while the Cougars get torched from deep. That’s a 10-percentage-point gap, and in a game with 20-25 three-point attempts, that’s a 6-8 point swing right there.
The pace battle is the other critical factor. William & Mary wants 77 possessions. Charleston wants 68. The Tribe’s pressure defense – generating 9.1 steals per game – should force Charleston into uncomfortable situations. The Cougars’ ball security is excellent, but they haven’t faced a team this aggressive and this fast yet in their winning streak.
Here’s the matchup that seals it for me: William & Mary’s ability to defend without fouling versus Charleston’s reliance on getting to the free throw line. The Tribe aren’t a high-fouling team, and Charleston doesn’t have the shooting to beat you from the perimeter. When you can’t make threes and you can’t get to the line, you’re in trouble against an elite defense.
The historical context matters too – William & Mary won the last meeting 90-75 in February 2025. They know they can score on Charleston, and nothing in the current data suggests that’s changed.
My Play
The Pick: William & Mary +2.5 (2 units)
I’ve considered Charleston’s home court and their winning streak, and the efficiency gap is still too massive to ignore. A 16-point difference in adjusted net rating doesn’t disappear because you’ve won a few games at home. William & Mary is the better team by every meaningful metric – they defend better, they move the ball better, and they have the tempo advantage.
The main risk here is if Charleston slows this game to a crawl and turns it into a rock fight under 65 possessions. But even then, the Tribe’s defensive excellence should keep them in position to win. I’m projecting William & Mary 78, Charleston 73 – a comfortable cover and potentially an outright win.
Charleston’s streak has inflated this line by 3-4 points. The Tribe should be small favorites on a neutral court, which means getting them as dogs – even small ones – on the road is value. Take William & Mary and trust the efficiency numbers over the recent results narrative.
