How much do top-level coaches such as Brad Gilbert and Larry Stefanki get paid? How much do players make for endorsement deals? I know the range is significant, but what is the range? In respect to other benefits, how many clothes and/or rackets are given to their athletes? Obviously, guys like Federer and Nadal get as much as they want of whatever they want, but does it work for someone not in the top 20? I read that Federer's deal with Nike is for $70 million over 10 years while appearance fees are as high as $1 million. So, prize money would seem an almost insignificant portion of their overall income.
