That's silly : I guess Americans will be happy to watch their provincial tournament
In France, when a player of this level asks for a WC, I believe he gets one ... despite there are more French players around rank 80-150 than Americans.
Right now France has 6 players in the 80-150 range and the US has 11.
I don't see how that's particularly relevant, though. I like Gasquet, but it's not like he's a superstar (at least not in the US, even with tennis fans). He's had some success and a ton of talent, but for the most part he's spent his career floating around in the 10-30 range. He just doesn't stick out as someone who's going to bring a whole lot to the table in terms of fans/viewers/sponsors. It certainly doesn't help that he's been out of tennis for almost 6 months because of a scandal involving cocaine. Tournament directors aren't going to be jumping up to give him WCs, especially when there are young local players trying to get in.
