Duke vs. Siena Analysis

Duke is the top overall seed and the top-rated team in KenPom entering the tournament.

However, the Blue Devils could be short-handed, as point guard Caleb Foster is out, and big man Patrick Ngongba is questionable.

Still, the Blue Devils won the ACC Tournament without that pair.

Cam Boozer is the best player in the country, averaging 22 points, 10.5 rebounds, and 4.2 assists per game. His ability to handle the ball, dish to shooters, and score for himself will be something Siena hasn’t seen all year.

Duke will have a significant length advantage. It’s the second-tallest team nationally (per KenPom’s average height metric), while Siena ranks 278th in that metric.

Siena played just one high-major opponent all season, losing to Indiana — which didn’t make the tournament — by 21.

This spread is hefty, but Siena will have no chance to score on the long-armed Blue Devils. This feels like a 30-plus-point Duke win.
