Rooting for him but he's got an uphill battle to make the team. MVS, Moore, Rice, James, and Toney are locks. Then you have Watson and John Ross who's the fastest guy.
That's a lot to get through but Justyn probably has the most talent. He's going to have to dominate but with his lack of experience I don't see that happening. He'll probably be a practice squad guy unless there's an injury.
Maybe working with Mahomes gives him a leg up on the other guys. He'd be a weapon if he unlocks his potential.
