“He may choose to keep doing what he’s been doing and not tweaking, and that’s his choice as a champion,” Federer’s trainer, Paul Annacone, said. “But for me it would be a shame. If you have a lot of weapons in your arsenal and choose not to use them, what’s the point in having them? It’s a matter of managing them a bit differently than he did a few years ago.”
In other words, Annacone (a consensus follower IMHO) intended to make Federer follow the current fad of flat hitting power players—turning Federer into a mini-Robin Soderling, or a mini-Juan del Potro.
Unfortunately Roger Federer is not that kind of player—nor does he need to be. Leave desperation power shots to the likes of Soderling and del Potro—all players who lack Federer’s control of the ball—players who cannot keep the ball in play long enough to create an opening.
Federer’s aggressive style against Djokovic is what lost him the match at the US Open. Instead of moving Djokovic around and creating openings for winners, Federer tried for winners, when the conditions were not yet ripe. All Federer had to would be to move the tiring Djokovic around the court until the winning opportunity presented itself.
Wham, bang, is not a winning strategy—and counter-productive for someone as talented as Federer. First round knockouts are rare in tennis (or any sport). You have to maneuver your opponent until you have a clear winner. Federer was even trying to hit half-volley winners off the baseline—which is as good as impossible.
Roger—please save yourself—please fire Paul Annacone!
