Following him since his commitment, you can tell how much work he puts in. This guy is dedicated to being a proper QB and not just relying on his physical tools to get it done. That makes me think it might take a little longer to get there but his ceiling is way higher. Seeing his approach to the game makes me think of Lamar Jackson. His build obviously helps make that comparison, but I'm referring to his actual game. Sims doesn't have Lamar's wheels, but then again no one else ever has (even Vick or Johnny Football at the college level), so he can't ride a busted zone read to a Heisman as a freshman. But Lamar dedicated himself to learning to be a QB instead of an athlete. That meant he didn't really get better results overall in college than when he was relying on raw athleticism, but he's worked his way to NFL MVP with plenty of room for growth from there. Totally different body, different system, and different pro potential, but Lil Joe is another who had the lights turn on when he could start connecting what he was learning with his muscle memory.
