I think Pitbull is really, really good but his cardio issues still hold him back against the top guys in the UFC imo. He looked improved in the last Curran fight but rounds 3-5 he still looked slower than the top UFC fw's (so did Curran but that was probably due to getting tagged so much). I just see guys like Mendes, Edgar and Swanson beating him in the later rounds if they can weather the early storm because he's not as talented as Aldo where he can win rounds even when he's fading unless he connects with something big. He does have power though so who knows but that's just how I see him faring against the top UFC guys for now. I think he loses Aldo even in the early rounds.
