Yeah, it is pretty damn puzzling. When the Spurs drafted Hill, they thought he'd be a shoot-first type scoring point. Turns out he's not a scorer at all. He's more like a longer version of Vaughn.
The Spurs have been linked to enough backup point guards that I think that they actually have turned the page on the idea that Hill will be able to step in and play backup point right away. I guess its not horrible if it just means Hill will spend a year in Austin and eventually turn into a player. But if he is a Marcus Williams level bust, the Spurs better consider bringing in a domestic scout that knows what he's doing .... someone like Isaiah Thomas.
