NFL and United Way giving back to community

On Tuesday, Nov. 16, many (not all) of the players from different NFL teams will team up with the United Way and give thanks to the community. They will build schools, houses, and do all kinds of things to help the community. This program has been a big success in the past. http://www.nfl.com/fans/story/7891771

I think it's great what the NFL players are doing, but I wonder if it's only for publicity. They need to be doing more stuff more often. Most of them are multimillionaires, and some don't even participate in this. There are some players that really do give back to the community on a regular basis, others don't at all. If it wasn't for the fans, none of the players would have jobs. ALL of the players need to be giving MORE back than what they are giving on Tuesday, if they are giving at all.
