He was a gifted player in his day and we all know he tried very hard to get some of that bling.
Because of the way his BBall friends tease him and rub their chips in his face (Jordan,Magic,Kenny, etc...) he has a tendancy to take it out on the younger stars who are trying to reach the same goals. This is what miserable people do.
He does hate on other teams and players besides the Knicks. With that said, I do find some of his commentary funny...like the time he was wearing a head band on the middle top of his head mimicking Lebron's hairline. I always respected his courage and he hardly seems to bite his tongue.
One thing thou...He might need to go harder with his weight watching regimen soon. I expect him to be putting on a few extra pounds after eating the flock of crows flying his way. He might look even more horrid in his black dress, heels and wig.
