At time, I also have felt they focused too much on Rodon throwing a change up instead of letting him try to dominate with two plus pitches. Hope we don't see something similar with Kopech.
Chris Sale is a future HOF. He played a big role in that success. I also don't know if Cooper's philosophy will translate well to the current strikeout/loft era
Being up here is doing him no good. He has no chance right now. Go to AAA and hopefully regain confidence. If not, he will be in Independent baseball in 3 years
