Chael might need 1 or 2, I think if Gustaffson wins he deserves a shot but the UFC clearly doesn't operate like a sport and if they had to pick between Gus and Chael they'd probably go with Chael and this is coming from someone who hangs off Chael's nuts like there's no tomorrow.
As for Nick, he might need one or two but I really don't see him putting together a streak at 170 unless he gets guys like Alves and Kampmann.
Then again I don't know what would be more satisfying than watching Alves kick the shit out of him.
THE PERFECT STORM
THE PERFECT RECORD
THE PERFECT FIGHTER
