How long were you in football? Was it long enough and were there enough 'lessons learned' that you can talk about the community of football as where you were 'nurtured'?
Oh yeah, they definitely do NOT intend to have you talk about your home town. Many people will talk about their literal community/family, but I know I talked about coming of age in the Army, another person in here talks about the LGBT community nurturing them, another talks about their years on the wrestling team.....and so on. If you do it right, the community you were nurtured in should have some semblance of relation to the identities essay.
