when i started playing in 6th grade, i was a tall, chunky kid. i played center on offense and either end or lb, depending on my weight at game time (had a weight limit, weigh above x lbs and have to play on line, and i was right at the limit all season).
stayed on line and at lb through 8th grade, changed schools before 9th grade and they put me at qb and safety (had grown taller and thinner). yep, went from center to qb. we were a smaller school (3a - mid size for bama classification then), so i also dressed for 3rd string backup qb for sr team. played in final game of season as both qbs got hurt. new kid, 9th grade (was typically only 10th-12th team), away game vs our rivals, yeah i was nervous, lol.
10th grade i played center again cause the center from prior year graduated and no one else had ever played c. plus had starting qb and backup coming back. also played s/lb on d.
11-12th grade the qb/backup graduated, i moved back to qb and s. we were mostly an option team, but i had some decent offensive #'s both running and passing. nothing major cfb worthy though. i was around 6', 150 lbs those last few years, didn't grow much at all.
we weren't very good (never made state playoffs, and only once went .500 while i played), but i was/am proud of my class of teammates. we went 0-10 my frosh year and progressed to 5-5 my sr year. they continued to progress and regularly make playoffs now. feel like we started that change.
i also long snapped for fg and punts. i got offered a couple of scholarships to snap (and maybe try other positions) at some really small schools (d3), but they were academic scholarships as they couldn't do athletic scholarships (ncaa rule). i chose to go to alabama because of an academic program i got into there.
