"John Isner is better right now than Andy Roddick has ever been"
"Yes, Roddick had a major, but in an era way less than today's. Isner plays better -- serve, net, forehand, backhand, never-die"
"I agree Roddick is more accomplished than Isner. And UR right, Isner has the ease of being on way up. But Isner in tougher era"
Do you agree with Greg?
