Frankie is a winnable fight for Penn, regardless.
I'm reserving opinion on how the fight will play out and how strong the Wandi/jackson comparison may apply...but I'll go as far as to state the first two fights can't even remotely be compared: Wandi finished rampage in their earlier meetings. Left him hanging "on the fence."
Penn/Edgar 1 was a close contest that I felt Penn won. Regardless of your opinion, it was a razor thin decision.
Penn/Edgar 2 was a clear and convincing win for Edgar, but at no point did he have Penn in danger. He out-busied him. He learned from the first point on how he could score points and he went out and scored them.
Saying he clowned him is like saying Weidman has "dominated" Silva twice. Or that Jon Jones' length advantage doesn't win him fights.
