I can easily see why he would take this deal as even the vesting option is super super low but man would it have been wild to see him hit the market!
I could have seen some teams offering him $20+ million for a year alone but its clear he likes Boston and is absolutely crushing it there! I'm not sure how many have heard about what he changed that has changed his whole career but its WILD!
It wasn't until he was with Boston that they told him to aim for a specific area (I want the ball low and inside) and the idea of aim small miss small kicked off! Before that he even says he was told to just throw his fastball without much if any direction! He's 37!!!! He's been in the league well over a decade and its only now he has been told to pitch to specific spots?!? Imagine what could have been if he had done so all along!
