My son switched football leagues this year, and I was happily surprised by how much attention was put on safety and concussion awareness at the start. I felt a little differently after the first game, when the other team threw two nasty hits, one of which was given to my son as he carried the ball. He came out of the game a bit dizzy a few plays later and his coach made him sit out the rest of the game as a precaution. I couldn't tell if it was the hit, the heat or the benching that had my son upset, but he was really fine. Except when he was asked to do any sort of work, then he suddenly went loopy...and started answering bananas. It's hard to monitor a smart-a$$ for a concussion.
