A big part of Shula's success is that he always had a good back-up QB, often a veteran who had been with the team for a while. Morrall was the greatest but Gary Cuozzo and Don Strock were great, too. Frank Reich was a great one for the Bills. Why don't NFL teams these days invest in a back-up QB- a guy with experience that they would bring in early, at the beginning of camp and learn the offense? It's usually some young guy who is more of an emergency guy, not a guy you expect to take over and lead a team to the playoffs. I hated it when the Colts decided to rest Peyton Manning for the playoffs in 2009 and turned the team over to Curtis Painter. Who?!?
