The twins also had a lot further to go to improve than the Six. The twins are attempting to be relevant and try to get into the playoffs. The Sox are trying to get to the second round of the playoffs.
Again. I disagree with the Rodon comment for sure and maybe the Kimbrel option.
There us no evidence that Kimbrel being in the team currently has kept them from making any other moves. It's all conjecture at this point. If they get stuck with him then it all changes.
