There are some crazy things I can dream up here, but few are very realistic. For example, maybe a team has a guy on the end of a similarly-priced rookie deal that they know they’re not going to extend and they are nervous about the market price. If Sacramento were shopping a soon-to-be-expensive Greivis Vasquez and wanted Gobert and a protected pick, wouldn’t the Jazz have to consider? Problem is, deals of that nature are hard to make because both sides are negotiating on potential, which is a difficult and subjective thing to commoditize.
If they wanted Vasquez they could have maybe had him in the off-season though. Not good for a tank.
