Taylor would kick his ass. The Ginger doesn't have the size, skill, and firepower that Pavlik had. JT would simply be too big for Canelo, and Taylor's shit stamina doesn't come into play here cause Canelo has shit stamina too. Taylor by UD, only because JT never stops anybody.
I can see Jermain having the odd anxious moment and maybe even on a really bad day getting stopped, but i think 9 times out of 10 Taylor wins a comfortable UD.
The version of Taylor from the first Pavlik fight would thrash Canelo. JT was actually very good that night. Pav just had too much firepower for him. But like I said, Canelo is no prime Pavlik.
I dunno if Canelo even beats coke'd out version of Whitaker that Tito beat. For all the revisionists who act like Tito had the skill of Ben Tackie or something, it's false. Tito was FAR more skilled than Canelo. Just a superior talent to Canelo in damn near every way.
