"The rise of spread offenses has created a position filled with bulked-up wide receivers who can run and catch, but offer little as blockers. Tight ends who can block don't add much to the passing game. "I think it's very difficult to find the guy who can both run and block simply because some of the offensive schemes that they are running in college. ... You don't get an opportunity to evaluate guys getting down in three-point stances," Atlanta Falcons coach Mike Smith said at the NFL owners meetings. "It's a tough position to evaluate." The most complete tight end in the draft is Brandon Pettigrew, the 6-foot-5 3/8, 263-pounder from Oklahoma State. Some Internet mock drafts have the Buffalo Bills taking him with the 11th overall selection, while others have him going a little later. No matter where he's picked, Pettigrew will be the first tight end off the board."
