NFL Draft Tracker is an interesting site, showing three mock drafts. They have the Pack selecting PJ Williams, CB, Florida State; Jordan Phillips, NT, Oklahoma; and Denzel Perryman, ILB, Miami.
Williams, according to the scouting report, could be the best CB in the draft, and Jordan Phillips could develop into a Pro Bowl NT.
I question the Denzel Perryman pick. IMO he's not a first round quality pick.
