Schwartz is a hell of a defensive coach...but he probably will never aspire to only be a defensive coordinator. He always thinks he can be top dog, and that is where he fails tremendously.
I don't care about experience. Being a great manager of people is something you are born with...it is not a trait that can easily be learned. Leonhard started in the league for 4+ years...he knows the game. Honestly, I'm not convinced at this point that Leonhard should be considered if Dom is to be replaced...or that he would even want to leave the college ranks. However, I'm starting to think the Packers should at least kick the tires and see what the guy is thinking about in terms of his career path if the Packers are going to be cleaning house on that side of the ball at year end.
