Kenny Smith -- $10k Blackjack's 'NOT SMART' ... But Ray Allen Can Afford It

Ray Allen is worth between $200 and $300 MILLION DOLLARS ... and even though it's "not smart" for the guy to play high-stakes blackjack, Ray can afford it ... so says Kenny "The Jet" Smith.

The "NBA on TNT" analyst was leaving LAX yesterday when we asked him about Allen's $10k-per-hand blackjack run in Vegas over the weekend ... a run that didn't turn out well for Ray.

"It's not smart, but it's like $100 to him," Kenny said ... "He's got enough money to probably fund the hotel."

Then, after estimating Ray's ENORMOUS net worth, Kenny dropped some serious wisdom:

"A guy who can play $10k-a-hand in blackjack, I'm not worried about him ... it's the guy who's got ten dollars and loses ... that's the guy I'm worried about."
