Cameron Boozer, Duke on Upset Alert? Fans Sound Off as No. 16 Siena Eyes Historic March Madness Win

No. 1 Duke received a rude welcome to the NCAA Tournament.

The Blue Devils surprisingly found themselves trailing 43-32 at halftime against 16th-seeded Siena in Thursday's first-round matchup. The Saints shot a blistering 55 percent from the field, with sophomore guard Gavin Doty leading the way with a game-high 16 points.

Duke star freshman Cameron Boozer did his best to carry his team with 13 points, but the Blue Devils made just two of their 15 attempts from beyond the arc.

Fans on social media were shocked by Duke's early deficit, with some wondering if one of the favorites for the national championship is already on upset alert:

Boozer and the Blue Devils will have to figure out a way to overcome the Saints' zone defense. Despite missing key players like Caleb Foster and Patrick Ngongba, Duke still has enough talent to make a second-half comeback.

The Blue Devils will have 20 minutes to keep their season alive, while the Saints try to pull off one of the biggest upsets in NCAA Tournament history.
