Many of us have been frustrated with Gibby not playing Smoak at 1B more consistently.
The stabilizing influence of his D can't be underestimated imo. While his range isn't great, his size and sure hands gives the IF a huge target and he can pick.
Collabello is so brutal on D. There is no need to play Edwin @1B. With Martin-JD-Tulo-Goins/Travis and Smoak this is a very solid defensive IF.
On O he has been inconsistent. Teams feed him breaking balls and change ups, but he is a SH power bat who has upside. His fWAR is only .4
