Right, and then we have to compensate that grass is slower now, etc, etc, etc. It is somehow going to fall in favor of Courier, but either way, Hewitt was truly solid at Wimbledon and grass in general. Hewitt even has a win over Sampras at Queens, though obviously those in favor of Courier will point of Sampras was out of his peak, but even as though as that may be the case, peak Courier which we can agree is 91-93, had only 2 wins out of 9 matches against Sampras in those 3 years.
I don´t see how comparison to Sampras is relevant when we´re talking about Courier and Hewitt. Yes, Courier had a losing record against Pete, but Sampras is one of the best players ever on grass and hc, and he was in his absolute prime in the 90s. And as you said, he was past his peak when Hewitt emerged. A prime Sampras would have kicked Lleyton´s ass if they had played on fast grass.
