He is a decent player. He has a soft touch around the basket. He can grab rebounds and score. However, his rebound rate has gone down over his career. He was among the top in the league he started. Now he's just above average.
And while he is in energetic and quick defender for a big man, he is undersized, gets himself out of position, and overall makes us a worse defensive team. He's not a bruiser even though he is big and does throw his weight around, he doesn't really intimidate anyone.
