It comes down to whether or not they want to pay top of market price for anyone at any position. Under Bill, they didn't. My guess is that they (Vrabel) won't for Higgins, either. Bill paid top of market for corners to take away teams #1 WR, but he never paid top of market for wideouts, and when they wanted more money they were either shipped out or not signed.
Vrabel outlines what type of player he wants at that position:
So, who is that? Who is going to fit that mold, be team first, and be mature enough to be held accountable? Not many guys will fit that right out of college, and not many will fit that who are at that position who play in the league currently.
