Can Roger Federer win a 6th US Open?

I think the competition on the hard courts are pretty tough and really could go to anybody. It used to be Federer was the uncontested best hard court player on the ATP, but now there are new faces like Del Potro, Djokovic, Tsonga and a much-imporved hard court player in Rafa, and of course the always steady Rod. I abolutely believe Federer can win a 6th straight US Open, but it will be a tough road. Federer has to be mentally fit and ready to give it all he's got. It's his title to take, it's up to him to win or lose.
