Just because someone has the tools doesn't mean they always use them, so Pac has longer arms, doesn't mean he can outjab Hatton. It all depends if Hatton can get inside and use his own jab.
I think there are a lot (not all ) of Pac "fans" who have seen a couple of his decent fights and think he is God himself, and also some more casual fans who actually use the ODLH fight as some sort of benchmark.Bad idea Hatton is still hungry and more imprtant still capable of living up to his own hype.
