I honestly could see him back in L.A. for many reasons: 1) It was obviously his favorite stop, 2) He'd have a legit shot at another ring, 3) there is absolutely no question whose team it is and will continue to be for the foreseeable future (short of a Lebron blockbuster), 4) Phil, 5) he's in close proximity to doing the entertainment gigs he loves, 6) He's mentioned it in public before, and 7) He could retire a Laker.
He'd play about 10 mins a game as basically a carnival trick to spell Gasol and Bynum and he'd have to take 2 mil or less per year. He'd pretty much just be a much more entertaining and beloved D.J. Mbenga.
