Up until his match with Rahimi he had won every match via 10-0 tech, with all ten points in each match being off of shots.
For the NCAA Folkstyle season a large part of it is based around conditioning. They will wrestle anywhere from 20-40 matches in a few month span, with their conference championships having up to 6/7 matches in a two day span and the NCAA finals also have up to 6/7 matches in a two day span. Cardio/conditioning is a large part of training.
It is also a reason some of our guys come right out of Folkstyle and do extremely well, even though they would not have been training Freestyle very long. Snyder came off a 2nd place finish his first year of college at 197lbs (~89 KG) and won a world title at 97 KG. Cox came off his season for the 2016 Olympics and dropped from 197lbs (~89 KG) and won a Bronze at the 2016 Olympics at 86 KG, purely off stingy defense and cardio. It's a thing.
