They were certainly great players, but Becker never got a No. 1 ranking due to inconsistency, Edberg only had two No. 1 rankings.People define ATG as 6+ slams but in my opinion It is more about defining your era, Even if someone walks along and wins 50 slams, Becker and Edberg will still be remembered despite only have 6 because they dominated their era.
Safin got zero.
