Ah, I guess I was comparing my weight to the wrong people (nfl players, all of them are 200+lbs lol)
I can throw well (power and aim), but I've never played before, so QB would probably be out of the question since I want to take this up at uni (at either Southampton or Sheffield), and experience seems to be very important to the position. I've got good legs, so sprinting and jumping are good. Although at the moment I train 100m and 200m sprints, so that may not be entirely useful for the bursts required in football. My strength isn't great compared to a lot of people, but I guess I don't get into situations where I'd find out.
Fearless? Erm, I don't care about getting hit if that's what you mean.
