The former top-rated recruit in the country, Nkemdiche has played a key role in the Rebels' rise up the polls this season. After switching from defensive end to defensive tackle, he has occupied space in the middle of Ole Miss's defense, recording 14 tackles with one sack and a pass broken up. As a freshman in 2013, Nkemdiche recorded 34 tackles with eight for a loss and two sacks.

Nkemdiche and his brother Denzel, another key cog in Ole Miss's defense, were both suspended for part of last year's Music City Bowl.
