In coaching kids throughout the years, i often have seen coaches gravitate to the better more natural wrestlers. It is easy to coach one of the "Zach Roberson"-type kids. No offense to Zach, an awesome wrestler and student athlete.
I think it is important to have coaches pay attention to all the wrestlers of all skill and ability levels, i think for safety and liability Kansas is wise to make sure a coach is matside.
My first year of coaching high school as an assistant, my head coach; during a major tournament, sent me to coach a kid who had limited success but was always butting heads with head coach. He was facing a very good wrestler,
what we found out is that this "uncoachable" kid was more comfortable to my style, had some success and for the next 3 yrs was virtually unbeatable in high school.
