I'm a huge Frankie fan, and I honestly don't know. Something was wrong with Aldo against Hominick. Could've been the weight cut or the sickness, who really knows, but SOMETHING was up with him. Gassing after the first round? Come on. We watched him beat the hell out of Faber for 25 full minutes and he acted as though he hadn't even started. Something was wrong, and he didn't fight at his best.
With that being said, I think back to the first round of his last fight with Maynard and Frankie was everywhere. Maynard isn't known for having huge power in his hands yet he rocking Edgar left and right. If that was Aldo, Edgar wouldn't have been able to get back up. Aldo is a lot more brutal, and even though he's a division lower, I still believe he has more pure knockout power then most Lightweights.
Edgar isn't helpless in this fight, though. His wrestling and conditioning is second to none, and if he can keep Aldo on his back he could possibly win. My only issue with this is that Edgar doesn't always keep the fight on the ground, no matter whose he's fighting. Eventually, he would let Aldo up, and that's dangerous. Not to mention Frankie would have to do this for 25 dangerous minutes.
I can't pick a winner, though. This is one of those fights like Silva/St. Pierre where either guy could take it, and I'm better off just flipping a coin rather then sitting for hours and hours trying to decide who will win.
If that fight does happen though, the fans will be the real winners.
