What would shock you most?

I'd be really imressed if Vargas KO's Mosley.

Nah that's nothing. :) Seeing PBF being K.Oed by an opponent like Sphinks would shock me to death. :D I would go into a coma, if I ever saw that.

Mosley being TKO'd. Vargas doesn't have his old strength/power. Toney will get hit, so it's a real possibility he might get TKO'd. Seeing Vargas knockout Mosely or Seeing Peter knockout Toney

Vargas>Mosley Toney is master at taking punches rolling and ducking but his time has come.

I think Peter winning by KO is more shocking. He couldn't even KO glass jaw Klitschko. Plus, Toney's defense is the best in the higher weight divisions. At least it looked like Vargas was hurting Mosley before the stoppage and Mosley takes chances so a KO punch could land.

Seeing Vargas KO Mosley. We all know about Mosley's chin, but Vargas doest have the power that Peter has.

The latter. I agree, but really the shock would subside in a couple hours if either occurred, given their recent disappointments.
