Harpring would be a perfect swingman off the bench behind Peja AND Bonzi. Probably eat just about the full 24min (or whatever) available at those positions and make us largely immune to injuries there. Bad for the kids -- but the time for our starters to win is NOW, so getting a perfect fit 6th man type like Harpring would be golden. Good smarts, good toughness, score inside and out. We'd be completely set at the 1/2/3.
Meanwhile, KT is mostly a pure small 4 -- Harpring eats the minutes he would have eaten at SF (if indeed he would have eaten any) and there are only about 10-12 available behind SAR. Not worth it, and for our needs a bigger more defensive player is a better fit to gret those minutes anyway. A new Pollard, whether it be Skinner or somebody better. Meanwhile we've shed a bad longterm cotnract and gotten back an ending contract in Harpring. We'd also be in much better position for next summer if Peja decided to walk. Ltos of "flexibility" as Geoff would say.
Its a clear win all the way around for us. But you're depending on Zeke continuing to be an idiot. Actually that's a pretty safe bet. So you're also depending on Larry Brown being an idiot (not sure if he was involved in the KT signing before he left Philly, or left Philly BECAUSE of the KT signing

), and on Jerry Sloan in his dotage being able to put up with a brainless heaver like Crawford. The anti-Stockton/Hornacek.
