I'm a fireman and I work with a guy that played OT for 4 years in the NFL, 2 yrs with the Colts and 2 yrs with the Cardinals. He was 6'10" and 360 when he played but now has "slimmed" down to 320. We played on a city league basketball team and I was very surprised how athletic he was on the floor, not just big. The last few summers we play Ultimate Football (similar to Ultimate Frisbee) and I am again amazed how athletic he is running, jumping and catching the ball. Many of us firemen consider ourselves athletic, most played high school sports and a few played in college. There is a reason this guy played D-1 and a few NFL years. Obviously the size at his position is needed, but he is an outstanding athlete also.
