It's weird.
I can't think of another combat sport, or any sport, where a 1 fight novice (against a real plum) goes against a guy with title defenses as a heavy weight champ in the history of the sport. Statistically Silvia is the most successful heavyweight of all time in the UFC.
Should be an easy win for Tim, but after the Ray Mercer fiasco who knows.
Please win Tim, for the sake of MMA.
