I have a problem with Sampras. He dominated a fairly weak field. An inconsistent Agassi and Ivanisevic, Rafter and others of lesser talent provided limited opposition. Emerson also must be regarded as lucky, considering that after Laver turned pro, only Santana offered great opposition. Tilden also faced a relatively weak field, with only one or two serious opponents. Borg was fortunate to win five straight Wimbledons, as his game was made for clay, not grass. After Newcombe's decline, there were no great grass players until McEnroe came along.
