First, you have to define "great". Not to be flipid, but I think the benefits of kids being involved in wrestling weigh heavier then their ultimate wrestling resume. I know guys that have accomplished National recognition and others that were the "big fish in a small pond".....none of which matters when you are more then 18 years old for most of them. It is the impact of the overall wrestling experience that lasts and makes them individuals that I want on my team as friends and co-workers. All that said, if you want to measure "greatness" in the win column alone, my list is as follows in order of importance ;
MAT TIME
Quality work-out partners
MAT TIME
Quality coaching
MAT TIME
MAT TIME
MAT TIME
MAT TIME
MAT TIME
MAT TIME
Of course all of this causes a conundrum in "my world" as I am a firm believer in a kid getting the "full" benefit of his/her HS experience....aka. be involved and diversified in your interest. I am old school in thinking that if a kid is 140lbs. plus walking the halls, he has something to contribute to the football team as well....If he is blessed with speed, he could probably help the track, soccer and/or cross country team...if he grew up playing ball in the back yard with his buddies, he might be the best baseball player in the school AND a wrestler. Heck the kid may be comfortable and confident beyond any of his peers and be the perfect person to be involved in theatre or music (wrestling does build confidence!)
Of course all of the time spent doing these things means less time available for MAT TIME. Kids that want to be basketball players can go to any park or driverway and shoot baskets, baseball players can go to the batting cages or play catch, football guys can play catch in the yard, go 7 on 7, or a pick-up game at the park. Wrestlings equivalent is the open room or RTC and freestyle/greco tnmts. Seldom have I been able to go to the local park and wrestle without sirens being involved at some point. ;D
