I disagree. I have liked what I've seen out of JO lately. Who cares about his box scores. His is playing hard. He had some real big plays ( a block shot, two BIG rebounds) late in the fourth against the Spurs. More importantly, each game he is getting stronger and developing more confidence. Plus, it takes a while to fit in to your role as a Celtic player. Take Marquis for example. After his play last year I thought Danny was on drugs for bringing him back to the Green. However he has been the unsong hero of the team this year.
Remember, box scores don't matter for the Celt's. Only mastering you role. JO's role is to guard the hole. Keep in mind who's role he is filling in. Perks! Perk will never blow you away with a box score but I cringed at watching one of the early season games against NJ when Lopez scored close to 30. NEVER would of happened if Perk was there or JO is playing at the level that he is at now.
