You see how they were pre-fight and now post-fight?
No respect for Bradley, just straight excuses about headbutts. It was bound to happen with a southpaw vs a coming forward conventional fighter. It just happened to be bad luck.
Bradley basically was calm the whole fight, and I'm pretty sure the last few rounds he was going to win in better fashion. It wasn't at all phased by Alexander. Alexander had no answers for a guy who wasn't bending over and actually was moving his head and countering and coming forward with effective shots. He looked like he had no adjustments.
Anyway, Bradley post fight kept it humble and I bet even in a loss he would have too, something Alexander and his camp should pick up cause that attitude especially suffering your first loss will get him no where.
