The old adage about quarterbacks is if you have two QB’s, you don’t have one. For some reason, conventional football wisdom is that two-QB systems do not work. There are quite a few examples indicating such conventional wisdom is wrong. Some of them can be found in Alabama football history.
The most recent example of a two-QB system working is 2006 and the University of Florida. The Gators were national champions in 2006 while Urban Meyer used Chris Leak and Tim Tebow at quarterback. Leak and Tebow did not play an equal number of snaps and their roles were very different but they shared the Gators’ QB role.
