I think the only 10-12 year deals that have been signed since Jed took over are basically the shortstops from the past few years. I think Jed signed the one he liked the best out of that whole group. Judge was nine years, but he was always going back to the Yankees. Cole got the nine year deal, too, but I agree with not signing any aging pitcher to a nine year contract.
All the other 10+ year deals that have been signed have been extensions where the player wasn't a FA.
We really don't have much in the way of saying whether Jed would go 10+ for a guy like Soto.
