Favors, Gobert and Hayward will all come up for new contracts. As has been mentioned, $14-$15M won't be max money after 2016. You can conceivably pay Hayward and Gobert $20M each, Favors $18, Matthews $14 and Burks $10M and still be WELL BELOW the luxury tax line of $100M+ adding in other veterans and draft picks to fill out the roster. Exum comes up for a raise just as contracts are set to expire. If he busts out and earns the max, then Jazz deal the contract of Burks or Matthews if they're set to exceed the luxury tax limit. If we were contending at that point, I have a feeling Greg would be willing to exceed it for a year if contracts overlap.
We're also assuming Hayward stays. I hope he does. But we need to give him a reason. Read his blog; he spoke very highly of Gobert. So I'm optimistic. But he also talked about the correlation of being on a winning team and receiving all-star consideration. I think the clock is ticking. Winning needs to start happening next year and the year after.
