I think getting out of the Clarkson contract was huge for them. You can't pay a 6th man $13 M a year to jack up ill-advised shots on a young team.
As for Randle, I don't think they'll keep him either. If they let him walk after the season, they'l have room fro two max contracts and I think they are going to do whatever they can to lure Paul George and LeBron to LA with that.
Ok thanks @brandonp..I guess LeBron could handle Randle's minutes pretty well!
