I doubt it is an anti-religion rant by the NFL; every time a player gets injured, players from both teams get together on the field and pray.

We have all heard players on TV thank God for helping him make a play, or achieve an award, etc.

I don't understand why the league wouldn't let RG III wear a non-Nike shirt but didn't do anything about the other player's non-Nuke shirt.

According to NFL bylaws, players are prohibited from wearing clothing with personal messages on game-days.

“Throughout the period on game-day that a player is visible to the stadium and television audience (including in pregame warm-ups, in the bench area, and during postgame interviews in the locker room or on the field), players are prohibited from wearing, displaying, or otherwise conveying personal messages either in writing or illustration, unless such message has been approved in advance by the League office.”
