Sampras is one of the all-time greats. His great strength is his dominance on the fast surfaces and mental toughness/clutch play. The weakness he has, relative to the other all-time greats such as Laver, Borg, and Federer is his play on clay, the slowest surface. So, he does have a little less versatility than all of those other three players, but he counterbalances that by being accomplished on the fast surfaces. Plus, if you want to pick one tournament to win a bunch of big titles, Wimbledon is the first place to choose.
