My 12th grade year in high school i played my heart out that year. It was before our most watched game and i was in the game playing linebacker the coach sent me on a rush and as i ran full speed into the line burst thru the line and sack the quarter back. When i hit him the stands went wild but i stayed on the ground. The coach ran out on the field to check on, later that day i found out i had a level two shoulder separation. That next week i played even tho it was hurt. I never been the same ever since.
