Roddick came on the scene toward the end of the Agassi/Sampras era and during the brunt of the Federer/Nadal/Djokovic/Murray era. It is considered the strongest era in men's tennis history.
Roddick admitted that he was not the best of his era, and perhaps lucky to be in the HOF, but as he said, he was proud to know that he "Guarded Jordan, went the distance with Ali, and pitched to Babe Ruth."
I saw his speech and thought that was a great quote.
