Vonleh will be 27 by the time the season starts. He will be 4 years removed from the season with the Knicks where he played 68 games, started 57, and demonstrated legitimate NBA ability. Since that season though, he has done pretty much nothing and ended up in China (I know people know the background but I am just setting the stage).
I really like the pick up and giving him a chance. I am predicting that we get a player that gives us maybe 10 min on a regular basis when everyone is healthy but who will be asked to play more on nights that Horford or RWill are out. I am hopeful that he can handle this role. He has demonstrated that he can play at this level in the NBA as he did with the Knicks over an entire season. There should be no issue with age or injury history or anything like that.
After a year in China, you would expect that he would be ready to do whatever it takes, play whatever role he is asked to play, in order to stay in the NBA. We'll see.
