I think it will. Kess seems like a smart fighter, and I'd imagine they will watch lots of tape and work on the things Kess didn't do well against Calzaghe. If he gets down about it and doesn't learn from his mistakes, he could be in for some real tough fights: Miranda, Taylor when he moves up, maybe Pavlik. They'll be tough fights anyways, but could be costly if he gets jaded about his 1 loss and loses focus. Time will tell.
