I dont see how Iggy opting out makes Denver idiotic. Its Iggy's choice to test the open market Denver has nothing to do with it. Now he will either get a long term deal from them or another team for equal or more money and be secure for the rest of his career.
The GM got a ridiculous salary from the Raptors, which makes sense he would go there.
The only dumb move Denver has made that it seems they've had control of is firing Carl. That makes no sense to me. Denver is one of those on the border teams that can really play well during the season but just doesnt have the right pieces or the "it" players to contend in the playoffs.
