Relative to their current fangraphs war projections, the guys I think have the best chance of surprising to the upside are:
Correa (3.7 fwar projection): It won’t shock me he if busts out with a full, healthy, MVP caliber season.
Paredes (2.0): Even if there isn’t a trade that opens an everyday spot on defense for him, I expect him to play the field most days and get more pa than they’re project him for. He will end up closer to 4 war than 2.
Cole (0.6): The projections are down on his defense and it’s looking likely that Meyers will be shipped out and Cole will be given first crack at the everyday CF job. He has immense ceiling with his power and speed; a season like Joey Gallo had in 2021 (4.4 fwar) isn’t likely but it’s possible.
Matthews (0.2): Cutting Dubon and Urias loose opened the door for Matthews to take on a super utility role, playing 2B, CF, and LF as they get guys more rest than in prior years. If another infielder is traded it could also open the door him effectively being the backup at 3B and SS. Either way, even in a bench role he will be a pinch running weapon. Hes a very high ceiling prospect and I expect him to for outstrip his 0.2 fwar projection.
Javier (0.9): Javier has always been underestimated by the projection systems. If he doesn’t get hurt he will easily more than double the 0.9 fangraphs is predicting.
