The pay is below sucky until you can make a name for yourself. You have to really want it to stay in it.
Although, it you want to get on ESPN, that's easy. Show a talent for YELLING nonsensical accusations and screams of incoherency without pausing to think about what you've just said and you could be the next Stephen A. Smith, Woody Paige, Skip Bayless, Tony Kornheiser, Dick Vitale...
Good luck anyway.
