To me, the Sox are a budding juggernaut and if Carlos wants to stay, he has to remind Boras that he works for Carlos and not the other way around. I think somewhere between 3/45 and the Keuchel deal could get it done. However, there could be way more money out there as there are always teams that are willing to bet big on stuff. I could see him getting a 4/80 offer from someone.
What is working in the Sox favor is the pandemic, as it could limit the number of teams that would be willing to pay up.
Imo the teams we really have to watch out for are Boston and the Yankees.
