I already told you it has nothing to do with the contracts, it has to do with the mindset. The Spurs loved Tolliver because he hit a hot streak in summer league, and it didn't pan out.
Just to provide you with some prespective, you compared Neal's contract to Haislp's. Where is Haislip? The contract has zero to do with how long he's going to be around. Neal does stand a far better chance of getting playing time even if he stinks because they're paying him. That's a pretty well-established pattern with the Spurs.
Let me be clear: Neal is not on the team, he got signed to a contract to keep him from going back to Europe. I've been on the record for a long time that the Spurs are idiots for falling in love with three pointers, because it's taken them out of what put those banners in the rafters. I'm well aware that the Spurs fall in love with three point shooters to the detriment of everything else. I just don't think it's a good idea. I never said they wouldn't sign Neal, I'm simply of the opinion that they shouldn't.
