He has a guaranteed title shot but he has to wait for the Bendo/Melendez fight first, so I think he wants to drop down for a title shot rather than wait again!
I'm sorry...I don't want to sound like a dick... but I really need to see some sources on that. At 155 Aldo is a monster. Really... I'm not a fan of Edgar... but Edgar's legs should've been smashed into several pieces after that fight... like anyone else's legs should be after fighting Aldo.
You check out the photo's and video of Faber's legs the day after he fought Aldo? It looked like he was trampled by a dozen horses. No ****.
I'm sure Petis can't be THAT crazy... like if he's told he has to wait till the end of this year for that title shot, really no big deal.
