Since their fight Pulver's gone backwards & Penn was gone forwards, watch their respective fights with Gomi.
I'll admit this much about Penn, he seems to lose concentration in some of his fights & cruises a la GSP & Uno (2nd), but if I was a betting man I'd put Penn over Pulver every day of the week in todays game.
I'm not saying he's a bad fighter, far from it, I just think it's a name from the UFC past that UFC fans are going ape for, when in reality he's a shadow of the man that left. A bit like Royce Gracie (alright, maybe that was a bit too low!).
As I said I may be wrong, but I'll wait til I see him in action against the likes of Edwards (if he returns) or Sherk.
