Just to point out that it's not really fair to blame Koby for any of that in terms of talent evaluation. Clarkson was acquired by Griffin and is still under that original contract. Nance also was acquired by Griff. Koby did extend him but we were a team to which FA's weren't lining up to go anyway, and we had a little space. His contract also gets significantly smaller moving forward, so he's tradeable.
Delly and Knight were both acquired as part of a package that brought us back picks. Them being overpaid relative to their talent is why we got the picks.
