What is the love affair with this guy? I mean it's not like Tomlin/Butler have the second coming of Woodson or Sanders and they're making him sit. If he's not playing, it's more than likely because he: 1) hasn't picked up the defense 2) hasn't practiced well enough to gain the coaches' trust or 3) Hasn't proven himself to be better than those that are ahead of him on the depth chart.
I mean it sucks that they traded a draft pick for what's looking like a 1 year rental on a guy that can't see the field for whatever reason. However, if he's not showing that he can get the job done, or hasn't gained the coaches' trust, why the hell would they put him out there?
