Knicks talk Walker
On the surface, the Sprewell deal doesn't sound too bad. If the Knicks are intent on trading Spree, they should do so before he loses his trade value. But it doesn't really help them to bring in another power forward, which is why the other suggested trade - a few of the Knicks' lower-salaried and expendable power forwards for Walker - might be the better deal.
From the Celtics point of view, I don't think Spree will really help them. Sure, Spree is still a good player, he's a great vocal leader and he has a lot of heart, but the Celtics need to add more inside muscle. The second deal makes more sense for them too.
I'm still not convinced the Celtics need to trade Walker in the first place. I feel they would be better off adding to the team, rather than making drastic changes.
