Meh, I think sometimes we can just lock in on the xFIP column on fangraphs and ignore everything else. Miller is young, throws hard, under control for three more seasons, and has been durable lately. It's also not like he hasn't gotten really good results - a 3.22 ERA in almost 600 MLB innings. He did throw a boatload of fastballs/cutters last season, but it was also his best season and came a big increase in GB%. I imagine he could adjust and use his curve more if needed. I was on the "Contreras is a top 2 prospect in the system" bandwagon before it was cool, but I think a Contreras/McKinney package is fair. Maybe not my first choice to acquire Miller and give up Contreras (if it came to that) with all of the pitchers that are available, but I would definitely be happy to have Miller.
