The National Football League has historically been opposed to players making personal statements with their equipment, especially in the Roger Goodell era. The league is known to levy fines on players for things as insignificant as putting the name of a relative on their eye black, and we at Acme Packing Company have criticized the league in the past for inconsistent positions on charitable issues and uniform policies.
However, this season, the league elected to pick one week to allow its players to wear cleats with specific personal messages on them in support of charity - so long as the league vets and approves the charity and the cleats are auctioned off for said charity.
