Those contracts on the backend almost always never workout, which is why I've never complained about not paying players on any 10+ year contract. It's like throwing away 100M imo but I'd be first in line buying an Ohtani jersey if it did happen. Like you're saying, if I was going to invest longterm in someone, it would be a Supreme athlete like Ohtani.
It's also why I'm so scared what a Vladdy extension could look like. Just say no to fatties.
