Leg 1: Clemson to win by 6+ points vs. McNeese State

Dimers is backing Clemson to win comfortably in today’s matchup with McNeese State, projecting the Tigers to take this one by a 7-point margin. That’s why we like them at the 6+ point line — it gives just enough breathing room while still aligning with Dimers' predictive model. Clemson’s size and physicality should prove too much for a McNeese team that hasn’t faced many high-major opponents this season. With the Tigers boasting strong defensive metrics and balanced scoring across the board, this is a classic case where the underlying analytics give us an edge. Dimers’ box score projections consistently highlight Clemson’s ability to control tempo and dominate the glass — two key factors in stretching the lead late. McNeese has shown some fight, but Clemson’s power-conference pedigree and depth make this a high-confidence leg in the parlay.

Leg 2: Gonzaga to win by 6+ points vs. Georgia

Dimers’ predictive model has Gonzaga winning by 7 points in today’s clash with Georgia — a margin that gives value to this 6+ point line. The Bulldogs (the Spokane ones) are starting to round into form, and their up-tempo offense should be a major factor against a Georgia team that’s struggled in transition defense all season. Dimers' box score projections highlight Gonzaga’s edge in both effective field goal percentage and assist rate, suggesting they’ll be able to create efficient shots throughout the game. Georgia’s perimeter shooting has been streaky, and if Gonzaga forces them into contested looks early, it could snowball fast. Dimers is bullish on Gonzaga's ability to dictate pace and build separation — a common theme in games where their talent and system shine. With the model giving them a 7-point cushion, this leg brings strong value into today’s parlay.

Leg 3: Texas A&M to win by 6+ points vs. Yale

According to Dimers’ box score projections, Texas A&M is expected to win by 8 points against Yale — which makes this 6+ point leg a strong value play. The Aggies’ physicality and rebounding prowess are major separators in this matchup, particularly on the offensive glass where they rank among the nation’s best. Dimers’ model sees that edge playing a big role in extra possessions and second-chance points, areas where Yale simply can’t keep pace. The Bulldogs play a more methodical style, but A&M’s pressure defense should disrupt their rhythm and force them into low-percentage looks. The model consistently flags Texas A&M’s efficiency in close-out games like this, especially when they can grind out stops and turn them into transition opportunities. With Dimers predicting a solid 8-point margin, this is a leg we feel confident plugging into the parlay.
