If this is the only move, then this will be a major disaster. But with the money they are paying him, I am not sure they can fix all the issues.
No consistent starter after Felix & Kuma
No outfield (Ackley and freakin' Saunders)
1B sucks (Choak)
No DH (Morales was solid at best)
Outside of Seager, Miller, Zunino and Franklin, the rest of the position players are a joke. And 3 of 4 those guys are listed on potential only.
And WTF is the deal with all of this "GREAT" pitching in our system we keep hearing about. Why is it that other franchises can get their young starters up and be productive? Go look at the list of guys
