Max contracts are going to be HUGE with the new TV deal. The advantage to locking someone up vs. matching a contract is you can give them that 5th year, I believe. It's a couple of years away, but maybe the Jazz should see if Gobert would sign at a bit of a discount: $80M/5 years. If he continues to improve at this rate, I fully expect someone to go $80M/4 as a RFA. Lakers went with a max deal for Hibbert, which Indiana matched. Rudy isn't the physical beast Roy is, but he'll be even better in many other ways.
Of course all of this assumes Gobert is making leaps in his abilities every year just like he did from year 1 to year 2. Way too early to tell, but given his amazing attitude, it won't be for lack of effort if he doesn't. I don't see him reading French novels during the summer and working on his tan on the Riviera. Or at least if he does, he'll also be playing a lot of basketball as well.
