I think practice has advanced over the years. More awareness that the grind of the sport wears bodies down. We used to live wrestle 3/4 of our practice time. I can't speak to all colleges but of the couple I know from the inside there is much more focus on situation drilling, specific position drilling, and full speed/half power "flo wrestling". Dodge ball and fun games in general really are great ways to condition and build team unity. What makes a coach like Cael so successful is his understanding that not every wrestler needs the same amount of every discipline. You aren't going to spend much time working on a cradle series with a Kyle Snyder type. Some guys are completely self motivated and some guys need a little push here or there. Great coaches figure out what each wrestler needs and figure out a way to provide that specific support.
