4 or 5 players might be better than they are now: Abrams, Ruiz (good now but I think could be really good if power appears), Smith (he had a great 2020, can he reach that with steady playing time at his preferred position), then I'd add Garcia (I have doubts) and Robles (doubtful but if he maintains his O it's 2019 Robles again).
Rotation has no upside other than Gore. Bullpen lacks a star, but OTOH I'm really intrigued by Thompson and Harvey.
Gray's got some upside. But I don't see any of those guys besides Ruiz, Gore, and maybe Robles (!) experiencing much of that boom case this season.
