One of the worst positions in 2019 for the Pittsburgh Pirates was catcher. The position recorded -2.1 bWAR, with the primary catcher, Elias Diaz, posting -1.3 bWAR and a 61 OPS+. The Pirates will enter 2020 with a not-so-flashy player behind the plate in Jacob Stallings, and I think he could be the team MVP by the end of the season.
This is far from a popular opinion, but hear me out. Stallings can impact the team in multiple ways. We obviously know about his defense. He recorded a +13 DRS, caught 40% of the runners trying to steal on him (26% was average), and was worth 8.
