In my opinion this team needs a little fire.
I definitely understand your point and I concur with the spirit of your thoughts but to me I would prefer to see that fire displayed by enjoying his teammates more when he has individual success and less enjoyment of himself.
That's just my personal opinion and I don't think it's a character flaw to see him express himself like he does I would just like to see more of a "we all share in my success" attitude if that makes any sense.
But I love the competitive arrogance don't get me wrong there.
