As Andy Larsen pointed out, Lauri has been the 13th best player in the NBA this season. It's completely unheard of for a rebuilding team to stumble on a 25/26 year old guy this good/valuable and not try to either turn him into assets even more suitable for its overall timeline OR, much more likely, start building around him ASAP.
We may still see the former option come to pass after Lauri signs his renegotiated extension, but the latter is definitely not happening.
It just feels like the fanbase sees Lauri as part of the scenery and doesn't fully realize that the likelihood of the Jazz drafting/acquiring a player as good as him within the next decade is almost zero.
