I was on the rowing team for two years and we competed against guys from schools supported with the resources of D1 programs (cough, wisconsin, cough, cough [even though Men's rowing isn't technically an NCAA sport, many of the bigger rowing schools still treat their male rowers to the benefits of D1 athletics, without having to follow all those pesky NCAA bylaws]) and the US olympic team. Does that count?
I taught a few athletes chemistry when I was a chem TA, and also knew some linemen from the football team, and let me tell you, I thought I was a big guy until one of them had to duck and go at an angle through a door to fit through it because his shoulders were too wide and he was too tall.
I was in the marching band for four of my five years, sophomore year the only section of calc that fit in with my Chem E classes was at the same time as marching band.
I was in the basketball band the last two years but I played at many of the games my first three years as a sub. And yes, I was there to witness the horrific decline of the program through all of the McD years.
I played a few games of flag football with ISU recievers. You want to talk about making it easy on the QB, I could throw the ball anywhere and these guys would get it.
I also have a few stories that I probably shouldn't tell, but they are Legen...wait for it.. dary. Legendary.
