I've sort of felt this way as time goes on. Tomlin inherited a solid SB winning team, and has just ridden that since he got the job. Along the way, key members of that SB winning team have left and he has replaced them with big mouth trash talkers and failed to develop any talent for the most part. A few high draft picks have turned out to be good, but where is the depth? A few busts in the draft on defense for sure. Where are the quality guys? Where is the continuity and leadership in the locker room? I think bringing Foote back was him grasping at straws to get that.
Troy and Kiesel are about to retire, and I think that is when you are really going to see this team go to the dogs. I don't think Tomlin is terrible, but I don't think he is nearly as good of a coach as he looks on paper. That team coached itself for a couple years post-Cowher. I haven't even mentioned the work Lebeau did with that defense, no credit for Tomlin there.
