To be fair,
(1) The direct comparison to Rudy Gobert is Dikembe Mutumbo... Greg Osterstag is more along the lines of Daniel Gafford, who was the starting center of a Finals team just last year. Those kind of centers still (and will always) exist; hell if the Knicks didn't choke to Indiana, we'd have seen another one with Mitchell Robinson in the Finals. The Osterstags (90s), Rasho Nestersovics (early-00s), Tiago Splitters (2010s)... Obviously as time goes on, we'll slowly but surely continue to see that archetype be more skilled... from the Plumlees to now the Isiah Hartensteins.
(2) the series before the Bulls, Utah swept a 61-win Laker team with 3-all stars (Shaq-all nba, Eddie-all defensive, Van Excel) and essentially the same core role players (Horry-27 yrs old, Fox-28, Fisher 23) that would 3-peat once the Jazz got old and Kobe matured. Malone equalized if not outplayed Shaq no different than Hakeem did 3-years prior.. So while Utah, Malone, and Sloan were mostly choke artists, they were also a damn good team who in that 2-year span dog-walked every team but the Bulls. And lost game 7 of the 1996 WCFs to the 64-18 Sonics by 4 points... otherwise they'd have potentially gone to the Finals for 3-straight years (96-98).
