Should Roger Federer be considered among the athletes of the decade? Abosultely.
Federer has to be on any shortlist of such an award, right along with Tiger Woods, Peyton Manning, Tom Brady, David Beckham, Kobe Bryant and Derek Jeter.
The difference for Federer, though, is that the Swiss has been that more consistent than his peers. Federer's finish the year on top FIVE times this decade, a feat no one else is close to. And he's done it in a sportsmanly manner. No Tiger Woods-type stories with Roger.
So yes, if there is such an award he is for my money most deserving.
