I think it's John. Not that Lamar Jackson owes him anything but had he come into the league with the wrong coach, he could have been a bust. It's why I thought Lamar would have been crazy to leave the team this off season. He's got a coach that knows his abilities and puts him in the correct place to use those abilities.
BTW, is Lamar in the HOF already.
