This is ESPN's analysis of Kelvin Shappard
What he brings: Sheppard is very instinctive and has a knack for finding the ball. He uses his above average diagnostic skills to get a jump on plays and is a reliable tackler with range just a notch below elite. He needs to play with better leverage taking on blocks but has the potential to become a solid starter in Buffalo's 3-4 scheme.
How he fits: This was the worst run defense in the NFL a year ago, and the Bills are really trying to upgrade their size and power inside with DT Marcell Dareus in the first round and Sheppard in the third. The Bills have decent ILBs in their 3-4 defense, but Paul Posluszny is a free agent, though he says he wants to come back. However, this pick is great insurance if he doesn't.
