That's going to be a lot of money again for something that's not going to be a sure thing at all.
You have Woodruff very possibly returning, likely need a spot for Hall, Civale is under contract, Rhea will have his option exercised, Tobias and Freddy are locks without even figuring what happens with Ashby or Misiorowski, among others.
I think Montas is here as a rental, nothing more. If you're going to spend that money to keep somebody I'd rather it be Adames.
