I want the Cubs to do whatever it takes to sign Ohtani, and I don't care how much they have to spend to get it done.
At the same time, I think it is a near certainty that he won't live up the value of whatever insane deal he signs. He will be 30 years old in the first year of his contract and we simply don't know how his skills are going to hold up as both a pitcher and a hitter. Teams will be paying for both, yet it only takes one injury for that team to lose both their best pitcher and best hitter.
If a team like the Dodgers or Yankees were to sign Ohtani and the deal backfires, they would continue to spend and find ways to work around it. If the Cubs sign him, they likely won't go anywhere near another big contract for the duration of the deal. The whole Cubs roster for the foreseeable future would be a house of cards stacked on top of Ohtani. I absolutely want to take that risk, but I understand Heyman's logic. Obviously the Cubs will have the money to spend if they want to, but I'm not sure they have the appetite to set the market on a historically large contract.
