Why would anyone want to see a 3rd match? Pettis has his number, beat him decisively via UD and Sub.
Grant is next in line, but the thought of Pettis vs. Aldo is quite enticing. Just imagine the standup war we'd witness. I hate to say this, but I'd favour Pettis as Aldo gasses in the Championship rounds. Had he faced champ* material in those previous fights (Homenick & KZ), he'd probably have lost.
