My coach was that type of coach. If one person in the unit messed up, the whole unit was punished. There was a time in high school, and I don't remember the circumstances, but I did something to get myself in hot water, and literally the entire team did up downs while I stood there and had to count them off. I was absolutely devastated, and I'm fairly certain I was in tears by the end of it. Effective punishment if you ask me. However, you have to take into account I wasn't a selfish assh*le and I cared deeply for my teammates, which probably isn't the case with a lot of players these days.
Every coach does it differently, but I like the team punishment better than the individual punishment. I think it lends itself to better accountability among teammates. I'm honestly kind of surprised Tabor is suspended given what we know about the whoopin' Lewis gave him, so he had to have instigated it pretty badly.
