I still want my team to at least try win a championship. I agree the Clippers gave up way too much for George, but at least they did it thinking they'd be conf finals/NBA Finals Caliber.
The Clippers will have to tank and start over, while the Celtics will continue their gentle downward path of "plucky 4/5/6 seed" that may or may not win a series every year depending on matchups and if they are hot that week.
I'd rather shoot for the moon, fail, and rebuild than put in work on the treadmill of mediocrity.
