Ugh, you're making me jealous... I loved playing football in high school, but I hurt my knee my sophomore year and couldn't really strengthen it enough to play the junior or senior year. I was a defensive tackle, and one that other teams didn't like having to face off against. I'm big yeah, but I'm quick out of a 3 point stance, and strong as an ox to boot...
Keep these years of playing in your memory for as long as possible, you'll end up missing the game from a player's perspective after school eventually.
