Does anyone really give Kenny a chance against BJ Penn?

Sure.

 

You got to use that pretty quickly then.

 

Florian is a very good celebral fighter. Very intelligent. He has the cardio to outlast Penn. And a very good chin to be caught there and there with Penn's excellent striking skill with his hands. Florian has a very good arsenal of striking, but he lacks a little power. His BJJ is slick enough to not be RNC'ed by Penn. I think Florian will try to make it a kickboxing fight. When BJ see that Florian is running away from him doing his leg kick there and there, BJ will take him down, and probably pound him out unfornuatly. BJ Penn's GnP is good and underrated. With his ability to trap an opponent arm, he will use that vs Florian.
Kenny has only a chance to win a decision, if he can nullify Penn's takedown. I think he has the tools for the standing. But he lacks the wrestling to avoid to being on his back vs BJ.

Sherk will always beat Florian because of that in my opinion.
