Quibbling over Koufos is like bemoaning the fact we let Humphries go. Decent backups, but not going to make or break the team. In fact, it was likely getting dumped that served as teh wake-up call for both. And, IINM, KOC didn't "dump" Koufos. Minnesota insisted he be included in the deal for Al Jefferson. Was Big Al better than Kosta? Um, yea, just a little bit.
As for Mo, KOC acknowledges that was the biggest mistake he made. But you look back at his rookie season and it wasn't all that impressive. Jazz already had two quality PG's in Arroyo (played in 71 games) and Lopez (played all 82 games). You can't look into a crystal ball and see injuries to Raul and an undersized combo guard breaking out. Wesley Matthews wasn't KOC's fault. It was a financial decision. Millers simply weren't going to pay $9M PLUS lose out on tax sharing to keep him. Again, he had a nice rookie season, but not spectacular.
