No, I think the "championships above all else" mentality is pretty silly*. I want some competitive balance to make the sport interesting (see: me hating college football), and taken to its logical extreme, championship-chasing undermines that (on top of devaluing championships period). Both the NBA and NFL thankfully have a salary cap that makes it so things don't usually get too extreme, but I'd actually like to see them become even more stringent than they are. I'm pretty happy when guys like Jokic take a trillion dollars and stay with the team that made them instead of going to whatever's the current hot destination. Somewhat conversely to me wanting more stringent salary caps, I'd also like to see stronger benefits in the NBA and especially the NFL for teams that draft players to be able to then retain their own players - for the NFL, something like a 10% cap discount if you drafted them would be pretty cool for encouraging homegrown talent to stay where they are, since the cap savings can then be passed on to pay those players more than competing outside offers. I like teams having consistent faces and identities over a long period of time, it makes them unique and memorable...as a opposed to the circus clown crap that happens too much in the NBA, where teams are made and then implode in the span of a couple of years.
*I mean really, even right after the Bucks won the championship two years ago, I said the journey was more fun than the destination, didn't I? Sticking to my guns here...
