Piku,
I hear you man. My HS wrestling coach would have made Knight look like Mr. Whipple. The guy was a lunatic and kicked the crap out of us, on and off the mats. On the other hand, our HS teams won 19 straight league titles, finished 2nd one year, then went on another run of 7 more in a row. He also bought us beer, and would occasionally allow a team member to use his apartment if the guy and his girlfriend were looking for a little "privacy". Of course all of this happened in the 70's, when there was discipline, respect for elders/people in authority, far fewer STD's, and 3.2 beer ! 😕
