Andy MacPhail aways said develop arms, buy bats. Regardless, I would open up the farm system and make the mega-trade for a youngish 2/3 starting pitcher. I really don't care which prospects they trade, but my preference is not to include Gonsalves or board scapegoat Kohl Stewart.
I personally doubt Stewart has the value to get a decent 2/3 back. But I'm bit surprised on your take on Gonsalves. I like him, don't get me wrong, but even if he breaks into the rotation in 2018, he's going to have some ups and downs making him at best an average pitcher in 2018-2019. If you can flip that for a guy who has already had the ups and downs and has figured things out, I think you do it. Yeah, you'll have 3 years of control, but that is still a good trade.
and that's coming from a guy that really likes Gonsalves.
