Who does horse racing have?

[Gander]

Baseball has Peter Gammons, Harold Reynolds and John Kruk, all excellent ambassadors to the sport if you will. All posess mountains of knowledge.

Now horse racing...Guys like Hank Goldberg, Mike Watchmaker and Andy Beyer are an embarrasment to the sport. Its become so bad that ESPN throws guys who know nothing about the sport like Kenny Mayne in there to try and make it worthwhile watching.

Why cant horse racing attract some star talent like the guys who do baseball?
