When it comes to the NFL, safety is a hot-button issue. While it's clear that the league needs to improve upon player safety to not only protect the players themselves but to protect the league. League officials have made several rule changes over the last few seasons, many of which sound good on paper but have diminished the quality of the game. While fans can watch a huge in on a wide receiver from a safety and see clearly that it's not helmet-to-helmet contact, thanks to TV angles and instant replay, referees have a hard time telling the difference in real time, causing them to throw flags when they're not needed. As players continue to grow bigger and faster, collisions will become more violent. One way NFL officials are thinking about attempting to curb some of the more violent hits is to increase the width of NFL fields by 35 feet, which would make them as wide as they are in the CFL. "The farther a player has to run in terms of contact , the less ferocious the contact is going to be," Bill Polian, a former member of the NFL Competition Committee, told CBS Sports. ""We know the most ferocious hits come from guys who are ten yards apart and lay each other out. You have fewer high-power collisions in the Canadian League than here." Of course, few high-power collisions could be a result of smaller and slower players as well. Even if the league does widen the field and it does make the game safer, there would be other effects, not all of them positive. Hall of Fame quarterback Warren Mood believes that one of these effects would give offenses an unfair advantage.
