some good ideas here.
I would like to add:
tov% as a displayed, searchable and sortable (in the draft center) stat. Also, the same for "fouled percentage". Both of these numbers are key ingredients of how a possession turns out yet are mysteries to most owners. You have to break out a calculator to figure out tov%, and that's simply no good. You can go to basketball reference and look up players from the late 70s on, but very few numbers actually translate from that site to this one anyway (just look at the differences in advanced stats).
