I'm confused, I'm not sure if people are trying to refute the idea that providing general height categories aren't needed because a 7'2 guard is useful, or are just stating it.
I think we've come to a consensus that drafting a tall guard can be useful given the right circumstances, but the rationale for wanting height included in the drafts is because drafting a tall guard when you're training guards is not as useful, and training a short center when you're training bigs isn't very useful either (unless you plan on selling them). As stated earlier, if you want players to keep and train their draftees, providing height is probably more useful than suggested positions.
