Very nice work.
For me, Lee is too stiff. Whilst he's waiting for the opportunities to punch, Junior will be outworking him. Chavez has a solid chin and, always willing to take a shot, has at least tightened up a bit since going to Wild Card.
I thought Molina beat him as well. But Lee, as @dftaylor
correctly stated IMO, is not all that natural a fighter. It does lend his style a real awkwardness, but he can overthink it IMO and shut himself down. Chavez will over awe him, and beat him up down the stretch. Chavez by stoppage 10-12.
I also wonder whether he'll say 'eff' the belt and come in overweight.
