As with Bradley coming into this season, I think patience is the operative word with JJ. He had no training camp and barely played during the regular season, and yes, he's thin, but he wouldn't be the first thin guy to have success in the NBA. He seems to have a good feel for things around the rim, he has good length, a decent midrange J, seems to prefer dunking whenever possible, can play above the rim. He was a first-round pick, so we've gotta give the guy a legit opportunity to prove himself.
And can he be as bad as or worse than Hollins? Highly doubtful.
