Cowser is the guy I'd trade and I like Cowser. I don't view this really as tough.
Kjerstad has more power potential and I'm looking at Basallo as a guy who can move Adley off catcher in a few years if Adley starts to slip. Or is DH/1B/C, to your point. Mayo is 1B of the future.
Yes, this team does draft college outfielders all the time. I wouldn't worry about dealing Cowser.
That said, I'm not that high on Cease as others are. Tremendous upside but he's not a clear cut #1.
Hearing this made my day.
