The difference is that Broadway Joe had a brain, could throw the football about 40 times better, was smarter, and brilliant as a Quarterback. There is absolutely no comparison whatsoever between Joe Willie and Manzeil. Namath could chew him up, spit him out, and make him like it.
I agree that Manzeil is one of the most electrifying college QB's in quite some time, but college isn't the NFL. He's not physically gifted enough to be out doing what it appears he's doing and then turn around and be anything close to a great NFL QB. If he keeps this stuff up those NFL defensive guys are going to kill him.
