I fully understand your point and it is valid. However,if you really want to get your point across, it takes players going one on one against a big man that knows how to play the game right. Spend enough getting embarrassed in practice can do wonders.
Lehigh wrestling has had a nice little run of All-Americans over the last few years. Every one of them though has been 165 or over. Coincidentally, all of our coaches weigh 170 or over. We have actually done a poor job developing our lightweights. Cornell on the other hand has had tremendous success with lightweights but have 2 excellent ones on their staff.
