You're also comparing a guy who's in his 4th(?) year to a true freshman making his first start on a dumpster fire team. Gerry had his moments and he's probably the better overall QB, but if BB is anything like he showed against Tulsa he will quickly surpass Gerry.
Gerry's biggest strength was his ability to run which also led to him getting hurt. His accuracy was highly suspect and that was with our best playmakers healthy.
