Indiana Pacers forward Jermaine O'Neal said he thinks racism might have something to do with the NBA's desire to put an age limit in the next collective bargaining agreement.

"We are seeking to raise that to 20 or two years out of high school. The NFL's minimum age is 3 years after high school. I'm optimistic the union will agree to some raise in the minimum age in the current collective bargaining," David Stern said in a recent ESPN.com chat.

O'Neal is an example of a player who went straight from high school and has become one of the league's top players.

"In the last two or three years, the rookie of the year has been a high school player. There were seven high school players in the All-Star Game, so why we even talking an age limit?" O'Neal said.

"As a black guy, you kind of think [race is] the reason why it's coming up.

"You don't hear about it in baseball or hockey. To say you have to be 20, 21 to get in the league, it's unconstitutional. If I can go to the U.S. Army and fight the war at 18 why can't you play basketball for 48 minutes?" O'Neal said.
