This is the nfl.com contact us website. It is the only link I have found to post complaints. This is what I have emailed them:
After following the Greatest Uniform Competition hosted by Dave Dameshek for over a month, I am very surprised and upset that the competition did not have a conclusion. It would appear that after a "small market" team won the competition, it was ignored. The winner was never even announced. I believe this is a slap in the face to the Panthers organization and over 1 MILLION fans who voted for their team. The Panther fans and fans around the NFL deserve a conclusion to the competition.
