Well, even Soxprospects hasn't said they were fleeced. Given the team they have right now, especially on offense, and the lack of starting pitching options both at the big league level and in the high minors, the opportunity to acquire a 27-year-old pitcher who has shown the ability to be an impact starter and has two more years of team control was likely too good to pass up.
Our team was already s*** in 2012, 2014 and 2015. Might as well try for the rings when you can.
