I would agree. Federer has so many plans to choose from. Most other players struggle to execute their one and only plan.That's not choking, that's just losing to a better player.
However, Fed losing to Novak at USO and Wimbledon was one of biggest chokes (if not bigger than Jana Novotna's choke against Steffi Graf). I don't know how he lost at Wimbledon - maybe an effect of his age. All he had to do was take two first serves and go big. Maybe USO was playing on his mind but this was Wimbledon with him on serve at 40-15. Novak had no business winning that Wimbledon. Sorry to derail the thread and it may start a war between Novak and Fed fans but since we are discussing "chokes", it was important to mention that.
