Pretty easy to see that Trouba was referencing Jose's defense in RF and to think that he's been anything less than an abortion out there is wrong. He has been an absolute train wreck this year, the worst I've seen from him. The only above average tool he has out there is his arm, which has been f***ed most of the season. He constantly does little things wrong that compound into extra bases, chances to score, etc.
For a guy who seems to be such a student of the game, his ineptitude on defense blows my mind. His mental errors- throwing to the wrong base, not keeping double plays in order, using his bare hand to pick up a bouncing ball drive me absolutely nuts. Physical errors happen, they're part of the game. Mental errors are due to a lack of concentration and focus and are completely unacceptable.
