This is the most inexcusable part, given that Jefferson was on a top 10 defense the very next year, and Millsap has been on a very good defensive team in Atlanta. Maybe Corbin's teams were just very poorly built to be a defensive team, but more likely than not he is just not a very good defensive coach. Like Frank says though, he was not a bad offensive coach. I really don't think he was anything special, though. Not disappointed the Jazz let him take the fall for the rebuild.
They defended okay with Millsap and Jefferson. Those teams were very poorly constructed for defense though. Raja Bell started 33 games. Devin Harris was the pg. Hayward and Favors were young. Earl Watson. CJ Miles. Josh Howard.
Yet Corbin still had them playing 19th in the league with that trash, and since everyone is forgetting, he still somehow squeaked the Jazz into the 8th seed.
