Top class opener SA produced are Smith, Barlow, Mitchell, Gibbs, that is far less than the amount of very good/great/legendary batsman AUS produced in Ponting, Harvey, G Chappell, Border, Waugh, McCabe, Boon, Junior Waugh, Hassett, Clarke, Walters for considerations for Jackson being picked an unnecessary stretch.South Africa has also produced many legendary batsmen buddy.
Also you are saying people would pick Richards. I doubt most would. Maybe a portion but put it on poll on cw and you might be surprised. Or maybe we lack imagination. You can't win it both ways.
Been around CW long enough & I've never seen a SA ATXI picked by anyone & Barry not included, if someone did it was certainly in minority & similar outside the CW world.
