Yeah I was factoring that in saying it would take a David Robinson level rookie year to get this roster over .500. David had vets like Terry mings and Mo Cheeks and very high end young players like Sean Elliott, Willie Anderson, and Rod Strickland, hence why they won 56 games.
Was also factoring that in. Wemby alone isn't giving you 22+ more wins even with a Robinson level rookie season. But a legendary rookie season from Wemby would be a prerequisite for being a .500 team short of say a trade for Lillard.
