Yeah might as well keep him
He's done a Hechavarria level decline in trade value. (One of the most interesting stories from the Davidi and Lott book was the disagreement AA and Farrell had about whether to play him or not)
The parallels here are very similar except it's too late with Gose - he has enough playing time that every knows he can't hit well enough. Plus Gibby is probably smarter at platooning and moving guys around than Farrell was.
