Houston blew it the most. The Warriors didn't really have something for him. Everybody else just didn't bother.
Houston on the other hand, if they knew that he can play at this high level it would be a different story. They might have packaged Kyle Lowry and anybody else to the Lakers right now for Gasol, knowing Lin can take the PG helm. Now is Lin better than Lowry, not. But he would be good enough for the Rockets that they can let go of Lowry and be able to land Gasol, finally.
Houston, bad, bad move.
