Really? He's a classic, throw-back center, and there have been tons of those. He's bigger and stronger than most, has good footwork, and uses his body well. On the down side, he almost never passes out of the post, and never shoots more than 5 feet from the hoop.
Unfortunately, that's no longer a prototypical center in the NBA. Guys gotta be highly mobile, able to shoot and help spacing on offense, and come out and guard on defense. He's probably good enough to do the dirty work in the paint, defending and rebounding, and my guess is that alone can get him a paycheck coming off the bench somewhere, but I could see clubs taking a pass too. His touch around the basket is really good, but teams want centers who can shoot at least out to the FT line.
