Let me start this by saying that wherever george goes, a wake of burned bridges is sure to follow. His personality varies from the most immature player I've ever played with to a condescending nuisance that acts as if he's multiple divs above everyone in the vicinity.
At first, he acts like he genuinely wants you to tell him what he's doing wrong. He acts like a decent player would. He stays up late talking to you about how he really wants to improve. But eventually, his ego catches up to him, and he starts defending his actions and siding against you whenever he can. Whenever he goes near his friends, he will toss anything you have given him away in favor of his new friends. This eventually leads to him removing you in angst and cutting contact with that entire group of friends.
You may think that this isn't related to being on a team or in game, but it manifests in his near-bipolar twofaced personality that will surely cause him to be very short with you when you realize that he isn't actually practicing to improve, but to say that he's improving. Similarly, he likes to place himself in higher divisions than he really is, then condescendingly offers to play pocket for a mid-steel team that he really wasn't better than.
I can't recommend anyone putting george on their team for his attitude alone, but his scout DM is around high-Steel and his soldier DM isn't much better. His gamesense isn't anything impressive but also doesn't hinder him a ton.
Really it's his attitude I'd avoid like spent nuclear fuel cores. Good luck to the team that tries to keep him aboard, he can be pretty funny sometimes.
