You can be Renaldo Nemiah or Michael Johnson and it guarantees you nothing. It's is a wonder that he has the God given abilities that he does, but, unless he learns to play football he'll just be a fast guy. I hope he is able to learn.
But, to answer your question, yes, he did have a step on his opponent.
