I know people that have been running 10-man rides since the 1980's in HS. I would not be surprised if a D3 college coach started doing it first as those guys are pretty creative. There is a difference between 10-man and pressure ridesSince we are on the subject and its fun to learn this stuff let me ask...was it only recently that the 10 man ride became adopted and was it Michigan who pioneered it? I tried to coach it last year to my sons team for about 5 minutes lol but you really need a VERY athletic goalie and ours was not the best fit even though he was a good stopper.
