He liked to show players that he owned the league. He would work extra hard and compete against star/great players.
He's ruthless and vindictive, though.
If you did anything to him he'd make a point to go after you till he's satisfied.
He was blocked once by some teammate on the bulls in practice. Every play after that he'd make it a point to pass his own man, then go over to shoot over the same guy in every possession.
Look at what he did when Rodman blocked him once.
