Actually I just went through the batting records during his career, and removing Sri Lanka so Richards can be on equal footing, there are only 3 other comparable batsman: Border (51.77), Miandad (55.28) and Chappell (54.38). Both Javad and Allen were pretty poor against the best team of their time, West Indies (in fact, Javad isn't too hot against Sri Lanka either and Border with S.Africa) so that leaves Chappell. Who, actually, probably does have a very legimitate claim to being the 2nd best batsman after Bradman. The rest either hadn't batted enough in that period to merit comparison and others (like Gavaskar) averaged below him.
