So fangraphs has his WAR as 3.8, and baseball reference has his WAR at 5.8. Not sure which is more accurate... Regardless I will stick with Fangraphs for the debate. Gray finished ranked #21 in WAR for all SP this season. Seeing some of the names surrounding his ranking, I would agree that he's not in the elite ace category. However, for the Twins, if they were to acquire him he would be immediately penciled in as the #1 pitcher in our rotation. And that's really what we're looking for at the end of the day right? An upgrade for our current staff? Trading away Berrios would be a tough pill to swallow right away, but I have my doubts that he would be close to the top 20 in WAR in 2016, maybe even 2017 too. If the Twins want to take the next step and be a 90+ win ballclub, it's going to take moves like this to improve right now. Otherwise there may be a step back in 2016 before there's a giant step forward for the organization.
