Hey man, keep it up. I'm not sure your age, but the older folks in our flag league are some of the best, as they usually have the best hands and are natural defenders, knowing how to play well on space (which is helpful in our league, where its 8 on 8 coed). Even if they lack the speed and athleticism compared to the younger folks, they usually make up for it in those areas.
Also, they make more money than those of us on our 20s, so they end up buying rounds afterwards, thus making them very valuable additions to our team.
