Sampras probably had Agassi's measure at his peak, remember he used to pull out those aces at critical times which would have been demoralising for Agassi who was such a good return of serve....
Sampras was brutal the way he played, would have been interesting to see him vs Federer but their careers didn't really overlap in any significant way
back to Flip, imagine what he could have achieved with his talent but Hewitt's tennis brain and application! Hewitt is a guy who gets the most out of himself. Lacks the power to make quick kills so he is always stuffed toward the end of a Grand Slam tournament but has guts and determination.
