You know what that means, right? Rondo and Perk, balling in Kentucky, K-I-S-S-I-N-G. Or something like that.

It also means, in all likelihood, that Rondo demonstrated enough leadership to invite JaJuan Johnson to work out at Kentucky with him. We’ve come a long way since Rondo was characterized as a brooding, selfish headache for the Celtics coaching staff, when Danny Ainge put Rondo on the trading block but ultimately decided the juice was worth the squeeze.

To recap what all Celtics are doing now:

• Avery Bradley just signed in Israel, but his deal includes an NBA opt-out for whenever the lockout ends.
• Paul Pierce and Kevin Garnett were most recently spotted at the NBA labor negotiations. Garnett was his usual animated self at the meeting, urging players not to cave to owners’ demands, causing a fellow player to say, “I respect the [expletive] out of those guys standing up for us right now.”
• Rondo (who will participate in Lebron James’s charity game Saturday night) and Johnson are working out together at Kentucky, as I just noted, where Johnson is preferably using the Glen Davis diet. Davis, in case you were wondering, has been relatively quiet this offseason. I am not sure what he’s currently doing, but I hope it does not involve 4 a.m. fights with whoever is driving his car.
• Jermaine O’Neal has not been heard from publicly, I don’t believe, since participating in the Impact Basketball Series. I imagine he’s now somewhere, either working out daily or trying to silly glue his joints back in place in order to work out daily.
• E’Twaun Moore is playing for Benetton Treviso of the Italian League with Brian Scalabrine. In their last game, Moore outscored Scal, 9-8. Fellow NBAer Jeff Adrien scored 10 points and some dude named Moldaveanu led the team with 15.
• Jeff Green, a restricted free agent, was last spotted playing in a handful of charity exhibitions. Sadly, I doubt he is spending much of his time mastering the box out.
• Gilbert Brown, an undrafted free agent who the Celtics showed interest in prior to the lockout, played his first official game (I think) for the German team S. Oliver Wuerzburg on Oct. 3. Unfortunately, Brown only played six more minutes than I did, finishing with two points to go along with one rebound. Former UMass star Ricky Harris led Brown’s team with 18 points, but alas, you probably don’t care.
