I'm sure there'll be some growing pains, but he needs to let the OC call the offense and he needs to divide his time among the special teams, defense, and offense. When you've earned a HC role, you're doing your team a great disservice when you're still trying to wear the OC visor. Unless you're just a proven badass, which in this case is just simply not the case, you should be the "walk around" leader...not the underpaid guy trying to do 2 jobs...fucking Jerry Jones, I swear!
