This is a joke right? I mean, your just playing with us certainly? The "only" difference is Kongo is a better striker than Sylvia? Thats the only difference you see? You look at Shane Carwin and Jeff Monson side by side, and you notice no differences? No Physical difference between Kongo and Sylvia either? More jiu jitsu training han Carwin? If you think Kongo would do anything on the ground but get the **** kicked out of him you have never seen him fight; Carwin, Sylvia, and Monson would all beat him.
