Pittsburgh Pirates' right-hander Mitch Keller's name has come up a ton in recent trade rumors, and rightfully so. The team is bad, and Keller holds a lot of value. The way he's pitching at the moment also gives Bob Nutting a chance to get out of the remaining ~$60 million on his contract. It all makes sense.
But while Ben Cherington has made some colossal blunders during his time in Pittsburgh, trading Keller may end up being his biggest by a mile. The sort of security that Keller brings to the Pirates' rotation is not something they can easily replicate, even with their vast amount of pitching depth.
