I think Phelps stripper and drugs antics, as well as the fact he has come across pretty poorly in the press since winning his medals hurt him. Bolt isn't American, and I don't think track and field is big enough to leap him over such well established US names. All the guys on the list have huge endorsement deals, and get a lot of coverage outside of their sport in the US. Maybe if it were a summer Olympic year, people would remember Coughlin's name. I am surprised about Vonn, given how popular she seemed during the Olympics. The LPGA has got to be concerned that there is not one rep on the list.
