Duke enters this East Region opener as a 28.5-point favorite, which tells the story of the matchup on paper. The Blue Devils have the talent edge, the depth edge, and the national title expectations, but this game still carries some intrigue because it is their first tournament game without Caleb Foster in the backcourt rotation. In a game where Duke should control everything, the biggest question may be how sharp the Blue Devils look while easing into the bracket.

Siena vs. Duke Preview, Injuries, Lineup News
Siena will need a huge performance from sophomore guard Gavin Doty to stay competitive. He is the Saints’ top perimeter creator and one of the few players on the roster capable of generating offense against Duke’s level of athleticism. Siena’s best team trait is ball security, ranking 57th nationally in turnover rate, and that will at least give the Saints a chance to avoid some of the empty possessions that can fuel a runaway.
Duke is built around Cameron Boozer, with strong secondary support from Cayden Boozer and Dame Sarr. The Blue Devils rank among the nation’s best teams on both ends and are especially dominant on the glass, sitting 8th nationally in rebounding. They also do not play particularly fast, ranking 282nd in tempo, which matters in a game with such a massive spread.
The biggest injury storyline is Foster. Duke’s starting guard fractured his right foot in the regular-season finale and will miss this game, with his tournament status beyond the opening weekend still uncertain. Reports indicate any return before the Final Four would be aggressive, so Duke is preparing to move forward without him for now.
Siena vs. Duke Prediction
Duke should win this game comfortably. Siena ranks 307th nationally in effective field goal percentage and 294th in scoring, which is a brutal offensive profile to bring against a Duke defense this talented. The Saints also rank just 239th in rebounding, and that is a major concern against a Duke team that can dominate possessions by controlling the glass.
What makes the spread more interesting is game flow. Duke plays slow, Siena plays even slower at 354th in pace, and that kind of tempo can make it harder for favorites to build enough possessions to cover massive numbers. That is part of why our FairPlay AI sees a slight edge toward Siena against the spread, even in a game where Duke is overwhelmingly likely to advance.
There is also the reality that Duke may use this game to settle into its adjusted rotation without Foster. The Blue Devils have more than enough firepower to pull away, but that does not necessarily mean they need a full-throttle, 40-minute performance from Boozer and the starters. If Duke gets control early, this could easily turn into a game where depth and rotation management matter more than margin.
Siena vs. Duke Best Bet
- Siena +28.5 (-115) Check out the best odds at FanDuel Sportsbook
Our FairPlay AI projects a modest +EV edge on Siena +28.5, with the model giving the Saints enough pace and ball-control support to stay inside this number. The core reasoning is simple: Duke ranks just 282nd in tempo, Siena ranks 354th, and slower games reduce the number of possessions available for a favorite to create true separation.
That does not mean Siena is likely to threaten the upset. It means the spread may simply be too large for the expected tempo and game script, especially with Duke also adjusting to life without Foster. Duke should advance with ease, but Siena +28.5 is the better betting angle.
