This is hilarious. I love your posts, dude, but there's NO way 3 months of Flaherty costs Mayer. Also, what half this board thinks would have been best is often very, very silly. Sale was worth 2.1 fWAR in a shortened season last year, and had an excellent xERA and a track record of being one of the best pitchers of all time. Jack Flaherty is having a very good year. He also pitched to a 4.99 ERA last year. And again, it's just three months.
I think if you look at the history of 3 month rentals, you'll find those deals often don't entail very much actually getting moved. I outlined what Montgomery went for last year, which wasn't very much at all. Two lottery tickets and a relief pitcher. Verlander got moved last year for two prospects, only one of whom was top-100 ranked. And that wasn't for three months, it was for a year and a half. And that was for Verlander, who's like, one of the best pitchers of his generation. Not Jack Flaherty.
