Hollins has been a back-up center for the duration of his career, and while his numbers are laregly underwhelming, it's easy to see why the Kings would want to sign him. He's a long, athletic big man. He blocks shots at a decent rate (1.6 blocks per 36 minutes for his career, 2.3 per 36 last season). He's also athletic and quick enough to run the fast break, which the Kings reportedly plan on doing a lot of this season.
