Don't understand this rating of the AO win by Connors in 74. It wasn't even in the top 5 events that year. Wim, USO, RG, WCT finals, Masters were. In essence, its a 2 major season to be honest.
If Connors had actually played RG, he'd have lost that "perfect" record -- Borg, Vilas, Oranted, Solomon, Nastase, Solomon, Ramirez, Vilas...
the field was too deep on red clay that year.
While the rest of the field was busy playing the WCT - Newk, Borg, Laver, Ashe, Kodes, Nastase etc., Connors was off playing the very weak Riordan circuit.

If emphasis on win-record, Federer's 92-5 record in 06 for instance was MUCH better considering he played a full field (3 losses were to Nadal on clay, 1 to Nadal on HC and 1 to Murray on HC)
