Nothing. He was never that good to begin with. Having said that, i never really rated Paulie that highly either. Both good fighters mind, just quite a bit short of being able to dominate 140....even in it's current state.

Diaz has just had that crowd pleasing style with a couple of half decent wins where his volume and tenacity has seen him win. He's a good fighter, but it's no surprise to see him being in close fights with other merely good fighters.
