We'll have to wait and see, I guess. I would assume that the revenue from that contract won't affect the cap until after the 16/17 season (which will be the first under the new TV contract IIRC). Gordo will be 3 years into his new contract, when the Jazz will have already re-upped Burks and Kanter and will be looking to re-up Burke.
Perhaps Locke's primary argument is that Gordo's new contract will be movable no matter what. I have a hard time believing a team will give up good assets for Gordo at $15-17mm if he continues to play at the level he played this past season. If Exum, Burke or Burks prove to be more effective on-ball players, and Gordo doesn't find his jumpshot, his contract will keep the Jazz from doing anything before 2018.
Second, he argues that the Jazz won't be any good so it doesn't matter. Awesome. If this is what the FO is selling, I'm finding a new team.
Third, he makes the argument that there's nothing else that can be done with the money. That's more than a little myopic IMO. We're already 3 seasons into the new CBA. The Jazz were able to land 2 1st round draft picks for cap space just a year ago. Who knows what will come available in the next couple seasons?
Finally, he makes the argument that the Jazz should keep him because they drafted him. Idiotic.
