Watching the B1G tour at Rutgers and Penn State and seeing a lot of the players with the soft outside padding on their helmets got me wondering why that is not something standard for practices to reduce concussion risks. I would think the coaches would want that extra protection during practices as I'm sure that the number of shots to the head/helmet are extremely higher during practice than games since the number of reps happening during practice are tenfold compared to a game. What are the downsides?
