UCONN was trying to target Povey and Davis for most of the game. Povey plays because he knows the system and the coaches think he won't make any big mistakes, even though he has in the past (see game versus Houston last year).
What I was surprised by is that Preator got replaced by Povey on the boundary CB position. I am not sure but I think Povey played free safety in their nickel packages and Bills moved over to KAT.
