I can't get behind the idea that a player option is actually a good thing for the team. It puts all the risk on the team and all the reward with the player.
If the Lerners were willing to build up to a luxury tax cap team, I don't think a 500 million contract with 4 year opt out to Soto is a good contract for the team. We're just all being clouded by emotional attachment to Soto here.
Actually, it is a way to control costs if you structure it so that the player is likely to opt out. For example, pay Soto $55 million a year for 4 years, then have the contract drop down to $20 million per year over the next 10. That's a $420 million guarantee for the player if he turns into Anthony Rendon, but it would be extremely likely he'd opt out if he has anything left at all.
