In comparison to other sports and different professions, I'm sure that Dexter doesn't make much for where he is in his given profession (#1 in the world- popular or not). Someone earlier said that a low ranking golfer can make $250k and nobody in the golfing world really knows him. Now put that against Dexter who is #1 in BBing and still nobody knows him.
I remember Ronnie being on Leno, Letterman, and Rosie O'Donnell among other lesser known shows. He was promoting his "sport" (lets not debate this here!) and trying to give greater exposure. People ripped on him for saying he was natural on air, but do you expect him to admit to using illegal substances for the televised world to hear?
I guess what I'm saying is, at least other people went out there and made an attempt to promote BBing and not sit back. Not that I'm looking for it, but I can't say I've seen Dex really make that effort.
