What I've heard is the NFL is worried about exposing their players to another 15 minutes of potential injury and the game is so much more intense most players are spent by the end of 4 quarters. A full additional quarter would likely result in more injuries due to exhausted players and in the NFL, injuries could mean huge money. Especially for regular season games, they want to limit that exposure as much as possible.
