Former Kansas State star Michael Beasley has become yet another reason NBA Commissioner David Stern will continue pressing for age limits on pro basketball players.

Stern thinks too many young players coming into the league are immature and can't handle the pressure and the money of the NBA.

Stern generally is right, and Beasley -- who is only 20 and played just a year at K-State before joining the Miami Heat -- is helping to prove Stern's case.

On Monday, it was reported that Beasley had checked into a rehabilitation hospital in Houston for a stay that could last at least 30 days.

From Yahoo! Sports:

Beasley’s frustration had been born out of a posed Internet photo on his personal Twitter page. In the photo, Beasley showed off a SuperCoolBeas tattoo on his back while two plastic baggies could be seen on the floor in the background. Some people have speculated on the bags’ contents, even though the clarity of the photo makes it difficult to determine.

Beasley was involved last year in an incident involving KU teammates Mario Chalmers and Darrell Arthur, at the NBA rookie symposium.

Beasley was fined $50,000 after he slipped out of a hotel room where Chalmers and Arthur were caught, against the rules, with women in the room.

And, as Stern knows, both Chalmers and Arthur were underclassmen, too, before leaving college early for the NBA.

All three, it should be noted, met the current general requirements that a player has to be at least 19 years old before joining the NBA.

But their actions, and those of other players, should make it easier to keep the age limits despite some attempts to get rid of them.
