Spurs don't have many trade options. the not fully guaranteed contracts of Fab and Bruce are somehow attractive for some teams, but we must not ignore that many other teams also can offer such contracts and quite a few are better in terms of salary dump potential.
so the Spurs will need to add something to get a quality player. and Hill is such an asset, even if the other teams won't exactly piss their pants when they hear his name. Mason is the other one.
so yes, I also think there is a good chance that Hill is part of a trade package this year. it's not to get rid of him, it will be to bring in someone who makes the team significantly better.
