timvp, well put. There are distinct differences between the players, but you get my drift. Generally, the positions are laden with with players with very similar skill sets. It's not like we can expect a major change of pace or a "different look" based on the subs utions.
FWD, I agree that Wally seems to be not worth it. I still like Cassell for the short term. And I don't think we can get an established player with the Big Three in place via a trade. I think the Spurs need to find a diamond in the rough... either a young guy that's been slept on or an old guy that no one wants.
Something to break up the monotony.
