The Utah Jazz have some cap space, but with the salary cap going up to astronomic levels "some" cap space becomes a Grand Canyon of Cap Space in a few seasons. So much so that right now the Jazz have more cap space (with guys on the books already) in 2017-2018 than the actual highest ever Jazz total roster salary. Ever. EVER.
While right now Gordon Hayward, Derrick Favors, and Alec Burks are on their 2nd contract (rookie scale extension), there are a bunch guys on rookie contracts as well (Dante Exum, Rudy Gobert, Trey Burke, Rodney Hood, and Grant Jerrett). The Jazz have a legion of guys on Non-Guaranteed contracts over the next two seasons -- none more important than Trevor Booker (only $250,000 is guaranteed for next season). That said, Bryce Cotton, Elijah Millsap, Chris Johnson, and Jack Cooley have proven themselves to be valid NBA-ish players of varying degrees.
There's the plight of unrestricted free agent Jeremy Evans to discover, and the idea of what Joe Ingles, a restricted free agent, could become. Both were positive about their personal and agent's relationships with the Jazz franchise and bigwigs, and want to be back. As does Trevor Booker.
That said, you have to recognize that this roster can easily be upgraded, and needs it in a few places. The team needs to save money for Rudy Gobert and Trey Burke, while keeping some stashed away for the rest of the guys who may need it -- including Gordon Hayward who has a player's option for his last season. I don't think that Dennis Lindsey, the Jazz GM, wants to break the bank on a free agent when so many players on the team need to figure out who they can be at the NBA level just yet.
There's money to spend, and some of that could be used for the European stashes: Ante Tomic, Raul Neto, and Tibor Pleiss. I think that both of those over 7' centers are an immediate upgrade over Cooley. Is Neto an upgrade over Cotton? Is there someone in the draft who the Jazz will immediately place in the rotation instead? There's lots to figure out still. It's only April. And what we know is that while the team goes into the NBA Draft with three picks, we could end up with just one dude, or three new guys from completely different spots. You never know . . .
. . . but what you do know is that the Jazz have money to spend, and positions to upgrade.
