You don’t see many 253 lb guys who get tackled backwards nearly every time. Guys come up on him and grab him by the shoulders and instead of him using momentum to pull the guy forward, he gets flipped backwards and falls facing the other direction. I’ve never seen that. He seems to have negative yards after contact. And I know that’s impossible with forward progress, but he literally goes backwards. But Randy Moss was about the same so I guess if you can run and catch the deep ball, there is a little something to hang your hat on.
