At first I thought this was about training and overtraining which is an issue with a lot of athletes, especially 3 sport athletes. But with further reading I understand how this could get confusing. My opinion, the coach knows the athlete and his style better than an "Academy" coach who doesn't know the athlete that well and does not want a brand new technique pushed on the kid mid season. OR you have the situation of "I was a sectional qualifier when I was in high school" type of parent who knows everything but has no idea what technique, style, pace etc. etc. his kid has because he does not see his kid in the wrestling room.
Best way to find out, talk to the coach. Not at before or during practice for goodness sake.
Which brings me to my next point, overtraining. It happens, and can cause a lot of atrophy in size, cardio, energy levels, and motivation.
I made it to sectionals, so I know what I am talking about.
