Some programs have coaches that work with certain wrestlers with a style that more closely resembles theirs, or allows them to coach to their strengths. You apparently work with a youth wrestling group...I wouldn't be surprised if somewhere along the way there was at least one wrestler that you didn't personally coach. Your son seems to have turned out alright, so why choose a public forum to bash a coach? Whether you intended it or not, you made a bold claim about that coaches program -- a program you are no longer a part of.
Mr Richards, I am guessing the source of all of your boo points is that although it is clear you are a fan of the sport, your online persona is that the world and the sun and everything else revolves around your son and your associated wrestling program. It does not. The sport is bigger than anynone wrestler, family, coach, or team.
Cheer your son on in his senior year, be thankful for the good memories, don't throw around bold claims about his team that are going to only put a target on his back. Don't obsess about his ranking. Kick back, just relax and enjoy the ride. Don't celebrate his accomplishments before they happen.
I hope your son has a great final year, and you find the willpower to do more reading and a little less typing.
