there is nowhere near enough evidence to say that he is superior to Grant.
You've been watching Ohio State Buckeye games, right? ;)
Kwon has Grant in every statistical category except tackles though he has almost half the tackles Grant does in maybe (MAYBE) a third of the number of plays.
Kwon is twice the player Grant is against the pass (even if that means blitzing on pass downs). In fact Kwon has more sacks and tackles for a loss....once again in maybe a third of the plays that Grant has been in.
Also, I've never seen Grant adjust the alignment of other def players. He may have or might not have had to yet, but I haven't seen it. Kwon adjusted his DTs the second play he ever played at OSU....after just making a tackle for a loss on his first ever play.
