Roger Federer is the greatest athlete of all time.

Different sports players have different life spans for instance tennis players only play till their early thirties many baseball players play till there thirties tennis is a much harder sport physically and that's why many guys who get to that age are not able to compete with the younger guys. "Federer does not have the strength or stamina to handle a sport like football." Depends what kind of football your talking about Roger was part of the Swiss junior national football team before he had to give it up to focus soley on tennis. I also can't help but disagree that football needs more stamina than tennis. They are a lot longer matches you don't spend half of it on the sidelines and conditions are generally harsher because of the time of year football is played while the outdoor tennis season is played in temperatures over 30C Celsius a lot of the time. Bo Jackson is a pretty tough guy playing professional baseball and semi-pro basket ball with a fake hip. But Federer made the finals of Wimbledon the Roland Garros and won the Us Open in 2008 when he had mono. He has also been battling a bad back for many years now and still playing good tennis. Also he has the record for most consecutive grand slam appearances. He has played 1126 tour level matches and never retired with an injury in any of them. You also listed a lot of impressive records awards and achievements that Bo has. However, that probably won't do your argument any good because when it comes to records no athlete on the planet can come close to Roger. Here is a list from http://www.rogerfederer.com...

Three victories at Grand Slam tournaments in the same season during three years (2004, 2006, 2007). At least four victories at three different Grand Slam tournaments.

Reached 16 out of 17 finals in tournaments played within a season (2006). 12 tournament titles in one season (2006; record shared with Thomas Muster). Those are so many records I'm sure you didn't even read half of them. Pete Sampras would probably be second in the running for best tennis player of all time and he doesn't have a French open tittle. Federer does and he won it in an era where Nadal has dominated on clay. He also has the second highest win percentage on clay behind Rafael Nadal if they weren't in the same era there is no way Sampras would be any where near Federer in Grand slams or weeks at number 1.
