Well, the big guy picked up where he left off getting 14 points and 10 rebounds in his NBA summer league debut. See the box score here: http://www.nba.com/summerleague/games/20100712/SACDET/gameinfo.html
He got mugged the entire game but kept his composure. Looks like that will be the opposing teams modus operandi until he proves his maturity (which we all know he has). I will say he did look a bit flat footed on defense with his legs straight. That being said he played more minutes against NBA level competition so you have to give him a break.
