Because you are blindly criticizing here. It's like me telling an astronaut how to do his job. Or a medical doctor, because I watched House, and fug it, it's close enough, right?
The fact that your "counter" is just saying "your argument is lame, can't believe you went there" proves my point. You are blindly throwing poo because the guy you wanted isn't here. Instead, we have Shula. Like I said, give it a chance, at least. If anybody knows the stakes, it's JR. If you think he's going to let Shula come in as OC without being damn confident that he can get the job done, you're crazy.
Did you watch last season? No not the last 4 games when Rivera suddenly decided to coach. We needed fresh blood and we just promoted from within. You don't get better by staying the same.
