Korver's defense was improving in Atlanta until injuries struck. He's not really the same player anymore. Ariza had a down year but you gotta hope that he recovers some of that shooting for next year.
No. But Ariza is a diminishing value asset. He's already 31 with 2 more cheap years in contract. At the end of the season he will be a 32 y.o player who relies on athleticism and is expiring. If we want to get good value back we should trade him this season.
