He should've sold when Ohtani was going into his last year but I think he just got defiant since everyone was so happy about him saying they would sell. I'm also not sure what offers if any ever materialized. Allegedly his children want nothing to do with the Angels so a sale will happen eventually, it's just a matter of if it's before or after Arte checks out.
It's also worth mentioning that from a price perspective he's actually a really good owner. They have some crazy good group deals, tickets are affordable in general even outside of that, and he's not extorting people for parking either. He's just absolutely terrible at the baseball side of things, can't/won't get out of his own way.
