Football, track. We are awesome considering we only had one legit D-1 prospect on our team, the QB. Only two teams scored on us more than once in 13 games; 8 defensive shutouts. One was an upper division team and the other knocked us out of the state playoffs.
I only ran track in college. Too slow for a corner even in D-II. I'd have been fine as a safety but making the switch just never occurred to me. I was deep in BB'ing at that time anyway.
