Yes.
He started playing midget AAA away from home when he was actually only 14 years old, which broke my heart to see him leave home at that age. That year he was wearing that helmet that shouldn't have been used past bantam. He complained of headaches all the time. No one on the team clued in that he had a concussion. His dad and I didn't even clue in. We actually chalked it up to homesickness and being away from home.
Now looking back we wonder if he didn't have a concussion for most of that year. He was frequently taking shots to the head in practice. We did actually go to the team about that and say, look, this has to stop, look at the marks on his helmet. Even on the back of his helmet there were puck marks where there isn't enough protection for sure. They didn't do anything about it.
