The New York Knicks legend Charles Oakley, who started his pro career with the Chicago Bulls in 1985, has an idea why the Brooklyn Nets are struggling so far in the playoffs … telling TMZ Sports the Nets head coach Steve Nash might be the problem:

“The problem with Brooklyn was I don’t know if Nash is the right coach for them,” Oak said at LAX this week. “I don’t know. Being a ballplayer watching them, you know, everybody say, ‘well, this and that, if you got Kyrie and KD’ but you still need somebody at that front seat.”
