Penn is slacking again?/GSP best PfP fighter?

penn obviously didn't train hard enough for this fight. fair and simple. he ged in the second round, and i don't care how tough of a fight or what kind of pace the fight is being fought at, if you gas in the second round you didn't train hard enough. gsp on the other hand kept the same pace he started with for the entire fight. he obviously trained hard enough for this fight and it paid off
