People keep on talking about these returns in the context of "well you'd have to work out an extension"
A. that extension is real money, which Ohtani may be worth, But you may also be spending money to replace the likes of Bello/Mayer+++
B. I don't think he's going to sign an extension, and I think teams now this, which greatly reduces the value of Ohtani. No matter how good he is, and I realize you can argue that right now he's the greatest player ever but that makes him worth a lot not worth unlimited resources. There's a dollar value on what a rental is worth and he's still just a rental. I listened to WEEI over a week ago and the literally were advocating trading Mayer/Bello/Casas for him. That's just beyond dumb.
If teams know this, the price for Ohtani is going to be a lot less than we think. It's still going to be high because it's FREAKING OHTANI, but it's not going to be an arm and a leg....just an arm.
