But it does have to do with gender. Leave it to Chris Fowler (or any of the male commentators, for that matter) to refer to Roger Federer's cardigan as a "Mr. Rogers sweater." You would think, after all these years, that Fowler would at least have a clue about what a traditional tennis/croquet sweater looks like, but apparently not. But then, why would a commentator want to miss an opportunity to "feminize" Fed? The white blazer, the white tennis bag (we heard about that on ESPN today, too), the cardigan--everything about Roger somehow gets turned into something "not masculine."
And while I'm at it, Fowler--No Doubt is not even close to being a "hard rock" band. You either need to get out more or keep your mouth closed. I vote for the latter.
