Jermain's problem has nothing to do with weight. He's a nervous guy. When he's in that ring he expends WAY too much nervous energy. I'm sure Steward had him as physically ready as he could possibly be, but you can see it in the tightness of his body how nervous he is. If he learned to relax in there his stamina problems would evaporate. You'd see Taylor as a racehorse in there, easily completing 12 rounds. But the guy can't get past something that made him tire out in the first fight with Hopkins and the first one with Pavlik and he had a much harder time with both guys than he should have.
