James has been the most front running player in the league for the last decade.
When things are going right he flexes his muscles, takes mock pictures with teammates before games, plays air guitar at half time and then when things sour he starts to scream at the refs, look for the fouls and pretty much laugh and shrug his shoulders at the refs as if they have missed the biggest call of their lives. It's funny for 2 guys the benefit from the officials and rule changes in this league the most that they pretty much complain on the court more than anyone
