In many urban settings lower income families do not have adequate land for their own gardens. Sometimes you will find a park with a community garden for families living in condominium or townhouse complexes but for the most part this is rare.
There are quite a few urban churches which have land which is not maximally used. Why not create community vegetable gardens where you invite local families to take a patch of the land to grow what they need/want. Make sure that some spots are taken by church people living locally so they can get to know their neighbours as they garden together. Sharing of the produce should also be encouraged.
It seems that every year every church calendar needs ensure that it steers clear of Superbowl Sunday as if it's a holiday of its own. Many churches also have projection systems. Rather than canceling Sunday evening activities on this day why not use the popularity of the game to the church's advantage.
Show the game with a message at half time. Invite the whole church as a church building event, make great snacks and invite friends, use it as a time to encourage family bonding during a football game rather than a time where the fathers ignore their children, etc.
