Duke vs Siena Prediction and Preview: NCAA Tournament First Round

It’s about the experience for Siena against a loaded Duke team on a national-championship-or-bust mission, looking to get in a light scrimmage before dealing with Ohio State or TCU.

Former Syracuse star Gerry McNamara’s Saints worked their way through the MAAC Tournament to get here, and there’s a little bit of history to work off of. They got to the second round in 1989, 2008, and 2009.

Meanwhile, this is Duke’s 48th appearance in the NCAA Tournament.

– Siena is about the defense, finishing 15th in the country, allowing just 65.7 points per game.

Why Siena Will Win: Slow Things Down, Hope For the Best

Duke will come into this banged up and looking ahead after the tough ACC Tournament run. Siena has to maximize every possession to extend the game.

It’s an interesting Saint team considering McNamara was an outside shooting god at Syracuse.

The Saints don’t make a thing from the outside, and they don’t do anything on the move – the fastbreak points are kept to a minimum. They rely on lots of passes, controlling the tempo, hitting their free throws, and not screwing up.

Why Duke Will Win: The Blue Devils Will Get Every Rebound

It’s all about the early intensity for Duke.

It can put this away immediately with a good scoring burst. Siena doesn’t have any ability whatsoever to mount a comeback, so as long as the Blue Devil focus is there, and there aren’t any second-chance points allowed, this will get out of hand fast.

The quicker Duke can get to the bench – this isn’t a deep scoring team – the better. There are already enough miles on this team’s tires.

Duke vs Siena Prediction, Betting Lines

To have any sort of a shot against the Blue Devils, you have to hit from the outside and move with a pace. Siena doesn’t do either one well.

Even so, it will come up with a mini-run early on, and then Duke will wake up and put this away. There’s too much size, too much defensive talent, and not nearly enough scoring pop from the Saints to make this competitive.
