a handful of college coaches make really good money. I think Cael makes $400,000 per year at Iowa State- thats about the same as a basketball coach at a solid mid-major.
there are another handful of guys like Ken Chertow and Gene Mills that have made a life out of running kids camps and HS camps. I went to Chertow's camp in HS. He also ran weekend mini-camps year round.
Then there another few guys like Rulon who are so famous they can get a few commercials and endorsements.
BUT, we are talking 1/100 of 1%. and it appears to be based on business sense rather than wrestling ability, save a few college coaches at big wrestling schools.
Side note: when i was at chertow's camp, Matt Hughes was a coach. So was Kurt Angle. I got to wrestle Hughes and got demonstrated a suplex on by angle. Something that gets overlooked about hughes is his ability to throw people... back then he was throwing headlocks like a mad man. This was before he got into MMA, and was wrestling at E. IL. He and his brother were punching each other in teh face and laughing about it. just thought id share.
