Five teams that are on upset alert in the men's Sweet 16

Michigan State isn't the most impressive statistical team. The Spartans rank 326th in the country in three-point shooting percentage (31.0%), but they offset their outside shooting woes by allowing the lowest three-point percentage in the nation (27.8%). 

Enter the red-hot Rebels, which are 19-of-39 (48.7%) from beyond the arc in the NCAA Tournament. If Ole Miss continues to shoot the lights out from three, it's hard to see Michigan State keeping up. 

No. 2 Tennessee Volunteers (-4.5) vs. No. 3 Kentucky Wildcats

Kentucky is not the team Tennessee wanted to see in the Sweet 16. The Wildcats swept the Volunteers in the regular season with an 11-point win at home and a five-point victory on the road, and the shooting splits in both contests were glaring.

In two games against Kentucky this season, Tennessee shot a combined 48-of-126 (38.1%) from the field and 14-of-63 (22.2%) from three. As for the Wildcats, they went a combined 51-of-102 (50.0%) from the floor and 24-of-48 (50.0%) from deep in those games. Kentucky might just have Tennessee's number this season.

No. 3 Texas Tech Red Raiders (-5.5) vs. No. 10 Arkansas Razorbacks

Arkansas has quickly turned into a Final Four contender after upset wins against Kansas and St. John's. The Razorbacks are deep with long, athletic bigs who relentlessly crash the glass and generate extra possessions. 

We not have even seen the best version of Arkansas yet, as leading scorer Adou Thiero might return to play for the first time since Feb. 22. Texas Tech better be ready for a war in the Sweet 16.
