I think a realistic ceiling is .264/.358/.410 (15 HR/20 SB), the floor is about where Frelick is now, and the most likely scenario is .242/.331/.353, which is a good enough OBP to lead off these days, with speed and defense. Almost certainly an everyday player, especially for us.
The problem at the moment is we only have about 250 PAs of this "new" Lara with increased power and a much better K rate compared to about 1100 PAs of almost no power and very high K rate. The "old" Lara was fringey at best. However, both of the HR/PA and K/PA stabilize pretty quickly, at least in the majors. He ought to get some chances this year because he certainly is not blocked by Lockridge/Matos/Jones/Perkins, or by Mitchell and Frelick against lefties.
I'm reserving judgment on branding him a gold glove caliber CF, because Chourio's outfield defense grades in the minors were about the same, and he was projected for CF. While Chourio is certainly a pretty good corner outfielder defensively, he has never looked comfortable in CF in the majors for whatever reason.
