Although the coaches cannot work with him, the players can. He can work in the S&C room and he can study film and move techniques no with existing players.

He has a lot of catching up to do, but Ryker Matthews could certainly get him started in all those areas early. Playing tackle is 50% about footwork only, and 50% about everything else related to the position (hips, arm extension, power jabs, hand and wrist ergonomics, positioning, body warping and timing).

I think Riker should help him with his feet, hips and body warp first. The rest comes quickly.
