Last year when he was drafted and had such a good camp and preseason, most of us were thinking he was the heir apparent to James Harrison. In the little playing time he had in 2010 he showed flashes of potential. He was drafted in the 2nd round with the thinking that over time he'd be ready to step in.
Fast forward to 2011. In Latrobe, linebackers coach Keith Butler called him out saying that he needed to have a sense of urgency and dedication to his craft. In preseason he showed very little even playing against mostly backups. When he played against starters he wasn't getting a good pass rush, and had very little push into the backfield. He looked to be out of position most of the time and just generally seemed to be lost on the field. While I certainly can't speak for what happens behind closed doors in the Steelers facility or anything, it seems clear though that he's got some issues to work through. I don't think it's a talent problem, he's got natural good pass rushing skills. He may just be taking longer to develop.
While Sly Sylvester has been penciled in for MLB, he did get some work on the outside as well. Should something happen to Harrison or Woodley, you would think Worilds would step in but that may not necessarily be the case.
The thinking is as of now, that the coaches could pull a move similar to what they did with Chad Scott back in the 90's. Move Timmons outside and then let Foote take over inside should it become necessary to do so.
It's not like his career is completely tanked yet, but he certainly hasn't done himself any favors in 2011 so far.
