Player to Watch on Sunday: Duke's Jahlil Okafor

We're likely seeing the last few games in the collegiate career of the Duke Blue Devils' Jahlil Okafor. The 6'11", 272-pound center is the leading candidate to go No. 1 in the June NBA draft. 

As he puts the finishing touches on his likely one-and-done stay in Durham, North Carolina, Okafor will be looking to solidify himself as the draft's top prospect and push his team toward a national championship.

On Sunday, he and the Blue Devils will face the San Diego State Aztecs. Okafor has a real chance to shine, as the Aztecs don't have a great deal of size in the frontcourt to contend with him. ESPN analyst Miles Simon believes the Aztecs might be able to keep it close if it's a low-scoring game, but he acknowledges the problem Okafor presents for San Diego State.

ESPN.com's Jeff Goodman recently placed the Kentucky Wildcats Karl-Anthony Towns ahead of Okafor for the top spot in the upcoming draft. This could be a signature performance for the Duke big man and a way to reclaim the top spot among draft experts.

Upset Watch: No. 11 Dayton vs. No. 3 Oklahoma

This year's NCAA tournament hasn't been overrun with upsets, but there's a chance Sunday's schedule could have a pretty big one.

Pay close to attention to the Dayton Flyers vs. Oklahoma Sooners game. Oklahoma is a No. 3 seed, but they have 10 losses this year and sometimes struggle to support star guard Buddy Hield offensively.

Dayton plays blistering defense when it's on, and the Flyers have been locked in lately. They have allowed just 54 points per game in their last two contests. If this is a low-scoring affair, the Sooners might find themselves in some trouble.
