Throughout this whole saga I have been of the position that they just need to put him on the IL until he is healthy. He is hurting the team occupying a DH spot that better hitters could be using.
I think the issue is that they know a 10, 30, even 60 day IL stint is not going to fix this. But they aren't going to disclose that due to whatever repercussions they think might come.
This is who Buxton is now. Maybe he has another surgery this offseason and makes a miraculous recovery but I doubt it. The Twins are not eager to admit to the fans what their outlook on Buxtons future is.
