I have never seen the kid play, college or pro. Not one minute. So I'm not going to jump to conclusions that have already been jumped to by many in this thread.
I look at it this way. He's a first round draft pick. This year's first round draft pick. I look at him no more or less differently than Kosta Koufos, Alexis Ajinca, JaVale McGee, or Roy Hibbert. He's raw and needs training and coaching. If by the end of next year, when his contract is expiring he is giving this team real, meaningful, productive minutes, then the experiment will be a success.
He just turned 22 and for the first time is going to be getting training at being the type of center he can be and not the type of center Nellie wanted him to be. If Clifford Ray can perform the same type of work with him as he has other big men he has worked with, maybe we can catch a break and get a diamond out of a pile of coal.
He's cheap, he's young, he's tall, he's longgggggggg, he's athletic, and he'll be the 15th guy on a 15 man roster.
He's worth the risk and I for one am going to support him wholeheartedly and give him the benefit of the doubt. He's now a Celtic. I know nothing to little about him the same way I know nothing to little about J R Giddens and Bill Walker.
So since I'm not about to start labeling them abject failures and calling them derogatory nicknames before they have even dribble a ball at the Garden, I too will not do that to Patrick O'Bryant. It's not fair. The kid hasn't failed this franchise yet.
