Coach, at about 145lbs, our son was the starting QB in an offense which ran a double wing, with the QB often being the lead blocker into the hole. They played a team who averaged 330lbs across the DL so that running game turned out to have question marks. Our son ended up throwing the ball all over the field. Team ended up making the area playoffs and he and his friends still get together and review films of him leading the pack into the hole. Our son played every offensive down because they had no back up QB, NONE!
The head coach was not invited back and more than a few feel it was because he did not use an offense which took more advantage of our son's ability to throw the football and which took too much advantage of his "blocking ability!" 
The transition to baseball went fine and he went on to have a wonderful college and Milb career.
When he showed up at college, the football coach was one of the first contacts wondering why he was late for Fall practice. From that point on, baseball was his only sport.
