Schwarber was producing as a plus MLB player his rookie year. He produced even better in the post season that year and last year, which, although a small sample, comes against cherry-picked superior pitching.
Although he could be like Todd Frazier. Best OPS in his first full year. Had a worse year next year but still about a league average player despite low batting average. Then became a productive all star for a couple years and has been a better than average player.
