He has multiple guys, but my hypothesis is that they have a metaphorical price tag on every one, and they aren't going to go over what they think a guy is worth or the length of the contract. Jed likes payroll flexibility and "clean books" (whatever that means) so he can grab a high AAV guy like Tucker.
They may also see Steele/Wiggins/Horton as the foundation of their rotation and don't like the prices for FA and trade candidate SP. They may see "the roster cliff" (TM, NSBB, 2026) as an opportunity to reset the core with Busch, OWNKC, Alcantara, PCA, Mo Baller, and Charlie Kirk's best friend.
And we don't know how much PTR and the sibs are paying for The Zachary, the sports book, and the AirBnBs around Wrigley. So he may have told Jed that the LT is a hard line (or that lower than the LT is the hard line), so Jed is having to reverse-engineer everything from there.
