I liked the fact that it made random NPC's potentially useful. You might talk to some dude on a whim and he ends up being a valuable recruit. And it reinforced Tidus' backstory as some blitzball star when you went out and led the league in goals. So from a worldbuilding perspective it kinda worked.
In the end it was just way too time consuming though. I see why they wanted to have an open-ended number of leagues and tournaments since if there was just one season you could easily fuck yourself out of the rewards but honestly the rewards being randomized is just kind of bullshit. The only real reason to play blitzball is the reels so just make those the default prize first time around and make any subsequent leagues/tournaments for bonus spheres or whatever. People just end up soft resetting until they get it anyway so drop the pretense and just make it the prize to begin with
