I think there's a clear distinction to be made between your (fair and quite interesting) point on bigs losing a year or more to injury, and this pandemic-related shutdown that kept players from playing organized ball. Technically, both were lost years, but no prospects this year (well, Wiseman specifically, I can't talk for every draftee) were redshirted, sitting out of most workouts and having to go through rehab instead. Wiseman most likely has spent a lot of time on individual workouts, bodybuilding, and generally training ever since he dropped out of college - he was probably one of the most well equipped draftees in terms of home-working once the pandemic hit, since he'd dropped out of college a while ago and was surely already training by himself or with personal trainers. Of course, that guarantees nothing in relation to his future development, and it's certainly not good to miss a year of basketball, but it's not a clear cut indicator that he'll be a bust (whereas I'll be keeping an eye on other bigs who lost development years to injury, sounds like an interesting correlation if true).
