Tim exerted a lot of energy early on and he could only keep up that pace for so long. The same goes for Pac, which is why he flurried a moments, where as both guys were throwing a lot of punches early. Tim also started being less effective, imo and thought he would try to catch Pac coming in like Marquez did. It really did seem like he was literally trying to pull a Marquez on Pac.
Tim Bradely got clipped by a hard right hook half way through the four . He came back fighting hard but it seem to finish his night. It fought in burst after that.
