Just like ZZtiger said...jab, jab, jab, jab...etc.
To say Fedor isn't a good striker is kind of insulting, considering who he has beat in the striking (Nog, Cro Cop). His overhand right is powerful and very dangerous for Tim (remember Randy's punch). Fedor also feints punches well to set up takedowns.
I actually think Sylvia is in a world of trouble here. When the fight goes to the ground he will lose, and in a 3 rounder against Fedor, its bound to happen at some point.
