I'd prefer more regular people who have no fame resume, so to speak. In Ethan and Jenna's case, however, neither of them, so far as I know, have really worked that fame as a career, Ethan has been through some serious health issues, and his season of Survivor was long ago enough that even though he won, I don't think he's still all that well known. He's also done a bunch of charity work, which is nice. I don't mind them coming on so much.
I think that professional athletes have some distinct advantages in the race too, but the NFL player is paired with his wife, right? I presume she's not a professional athlete. And snowboarders don't get as much attention as, say, football or basketball players, so the fame factor is less obvious there. Too bad they couldn't get some speed skaters. U.S. short and long track speed skaters don't have a lot of funding. Or lugers. Or a two man (or woman) bobsled team....
I'm kind of interested in seeing how the seventeen year old who sailed around the world alone and his dad work together too.
And yeah, a model/beauty queen free season would be nice. I've never supported an AR team strictly based on what they looked like, so I don't get why casting pretty people is so important. They must realize by now that some very popular teams have looked pretty much like most of the viewers probably look themselves.
