Austin Rivers might have preferred that training camp was optional for one member of the Clippers coaching staff.
Here's a hint: He's bald, on the yappy side and once played for the Clippers. And no, it's not Doc Rivers.
"I'm sick and tired of seeing Cassell, man," Austin Rivers said Tuesday.
Rivers was joking, of course. Sam Cassell was essentially Rivers' personal coach over the summer during workouts in Orlando, Fla., helping the Clippers backup guard improve his midrange jump shot.
They worked on footwork and stepping into shots at game speed by doing the same drill over and over.
