So small sample size doesn't apply to 2019 Gallo? He only played in 13 more games (71 more PAs) in 2019 than in 2020, and that 70 game sample is the hottest offensive stretch of his professional career (much like the first month of Duvall's 2020). If you treat Gallo's 2019-2020 as a full season, it looks exactly like Duvall's 2020 - smoking hot first half followed by an ice cold second half.
Again, not arguing that he wouldn't contribute at least something - just not sure what you'd give up for someone who has as many legitimate questions about him as Gallo does when you could just write a check for Duvall/Pederson/Rosario/Mazara.
Chris Young (the pitcher) is the new Rangers GM. Maybe he's super low on Gallo.
