Size, with Mason being 3-5 inches taller? Age when drafted out of HS? Both irrelevant? Ben Revere at age 20 was (similarly) putting up huge BA's in single-A, and even hitting XBHs more frequently than Williams; speedy OF is actually a relative area of depth in our system, too - so move over, Matt Szczur, somebody even slappier's in town! getting a 150 lb. project OF as the main prize for Garza might just make me physically ill I think you underestimate being bigger and younger...Revere was 19 or just about 19 when he was drafted out of HS (I'll try to find the article on age and HS/draft prospects). Williams is straight up a more interesting prospect....Saw the stats and didn't say Revere had a bad season at 20 or anything (good for him there, i guess). Don't think anyone said a thing about Williams headlining a Garza trade either. You can find a hundred guys with similar numbers...there's more to it than that and things like age, height, and other physical attributed ARE stats as well, often pretty relevant ones.
