1) Robin Soderling
2) Stan Wawrinka
3) Nick Kyrgios
Those are the only three players that I can think of who had legitimate “weapons” off the serve, forehand, and backhand. Many of the other players you listed have at least one weakness. Having said that, I tend to believe that power off of both sides is more indicative of raw power than power off the serve (by a small margin). In that regard, I finish out the list as follows:
4) Marat Safin
5) Rafael Nadal
6) Andre Agassi
7) James Blake
8) Thomas Berdych
All of those players hit with power off both wings (Safin and Nadal with more spin/control and therefore more power with margin, while Agassi, Blake, and Berdych being very flat hitters off both wings). After that, we get into the power servers who have one huge ground stroke to go with it,
9) Juan Martin del Potro
10) Andy Roddick
I give honorable mentions to Sam Querrey, Mark Philippoussis, John Isner, and Goran Ivanisevic.
Some of the other players you mentioned like Becker and Sampras I think are probably among the most “athletic” players we’ve seen in the sport (along with players like Gaël Monfils, Roger Federer, and Dustin Brown), but I don’t necessarily view them in terms of “raw power”.
