I'm sure some will call me crazy for this but I'd have a hard time pulling the trigger. The Indians will be priced out of any front of the rotation starting pitcher free agent, so it's vital for them to have homegrown talent there. Dealing Carrasco away leaves you with Kluber/Salazar/Bauer/Anderson/Tomlin. I just don't see that group winning a World Series over the next 3-4 years. I do think a group led by Kluber/Carrasco/Salazar could though.
I would give up Bauer/Chisenhall for Schwarber or Soler, though I doubt the Cubs would do that.
