In terms of things that sound great as cliches, but aren't always great in reality, I worry about interior pass rush as our calling card if the second level is unaware and doesn't adjust to cover running lanes.
Trubisky is young and possibly has some mobility not pounded out of him yet. I don't consider Stafford or Cousins to be dual threats, so that's nice. I hate the highlights when contain is lost, along with the pocket, and a QB takes it for a first down. However, it is nice to see a big ugly wrap up a QB with a pelvis-to-pelvis bear hug.
