Kallis v Sobers

It seems someone else also has recognised how underrated Jacques Kallis is and considers him the 2nd best all-rounder ever...here his stats are assessed versus Sobers and come out pretty similar. The difference of course is that Sobers could bowl three variations and, from what I hear, having not watched him play, was a more versatile fielder. So he edges it v Kallis, but not by much....
