Channing Frye Says Richard Jefferson Ran $36k Tab On His Card Before '05 Draft

Channing Frye had a "welcome to the NBA" moment before he even made it to the league ... 'cause he claims Richard Jefferson racked up a whopping $36,000 tab on his credit card the night before he was drafted!!

The pair of Cavs champions/former Arizona Wildcats detailed the 2005 rager on their "Road Trippin'" podcast this week ... when RJ invited Frye and his crew of 20-30 friends to go clubbing in the Big Apple.

The former No. 8 overall pick says the group included a ton of ex-Arizona guys like Gilbert Arenas and Luke Walton, Nets and Knicks players and fellow class of 2005 draftee "David Lee's punk ass" (RJ's words, not ours) ... but there was no issue with rolling deep, 'cause Jefferson had clout in the city after helping the Nets reach the NBA Finals.

"Richard, for lack of a better term, ran that demographic of New York," Frye says.

Once they got inside the club, it was bad news for Frye ... who willingly handed over his card to RJ after he asked him to "hold the table."

As it turns out, Frye says the massive group ended up partying on his dime the whole night ... with the final damage coming out to a mind-blowing $36,000!!

"They swipe it, they swipe it," RJ says. "He's just getting crushed. And this is kind of like a rookie hazing."

Channing rightfully freaked out over it all ... explaining, "The NBA money hadn't even got into the ozone yet, and my phone is blowing up."

"My s*** is still college s***, I don't even have an NBA check yet!!"

RJ insists he was looking out for his guy the whole night ... saying he was acting as a security blanket in case things went south.
