"O'Connor may be the most underappreciated GM in basketball. Nobody does a better job of sticking to a plan. O'Connor has committed to Jerry Sloan as his coach and finds players that perfectly fit his system. Players like Wesley Matthews, Paul Millsap, Ronnie Brewer, C.J. Miles, Carlos Boozer, Mehmet Okur, Matt Harpring and even Deron Williams would all have been successful elsewhere, but their success was magnified because they were all perfect fits for Sloan. O'Connor understands that you can't just throw together talent and expect it to jell. You have to find the right kind of talent, and for over a decade, he's done exactly that.
O'Connor has also done a great job managing the luxury tax, something that will always be an issue because Utah is a small market. Last season, he made cost-cutting moves that didn't affect his team's performance, then recovered from losing Carlos Boozer by trading for Al Jefferson. His one mistake was giving Andrei Kirilenko too much money in 2004, but otherwise, his record is impeccable.
The only thing lacking is a championship, but that's tough to do when you only get one top-five pick in a decade. O'Connor used that pick well, and he's made every last move count. That's the mark of a good GM."
