Team is on the cusp of solving two out of three of its most vital issues ever - stable arena and icing a winning team (with owner with the wherewithal to properly run the team seemingly here already with Meruelo). That holy trinity seems to be the key to franchise stability and we've really never had more than a fleeting taste of any of it.
For the arena - honeymoon phase at America West papered over serious arena issues, new arena briefly worked in Glendale before Westgate never amounted to much and battled with the distance factor, now ASU can be a placeholder for probably the proper amount of time until a stable Tempe project can finally provide a checkmark in the arena box.
For the winning team - think not much has to be said here. They were good for a bit at first but still didn't advance in the playoffs. The one run to WCF was great. None of this was ever sustained success that could be built on. Team is in promising hands now, sure you can question if they'll get there, but really the best part is that the fanbase's focus can be on the team itself and not some owner search drama and arena drama.
For the owner - he's stable, has money, has been spending it on the team. Some bumps along the way, but everything is going in the right direction and he's a dream compared to all other ownership this team has ever had.
Think with the solid ownership and the arena on its way, it's much easier for the team to take the right steps to become competitive, and the right kind of competitive where we have a good team for more than a single season or so. That's the key to building up a sustainable fanbase. Providing a run of competitive years will create lifelong fans who will at least still consider spending on the team when its in lean years again. We've essentially never had that and have been building a fanbase on hard mode this entire time.
