Quote: Big Picture "That's inaccurate. The NFL itself started as a league confined to the north-east and mid-west, but the sport was already played in colleges across the US by then. The NFL season has lengthened gradually over the years, with the last change going from 14 to 16 games. They now play over 17 weeks and are investigating options to make their season longer.'"
That's misleading. 32 teams play 16 fixtures over 17 weeks (one is a bye week).
There are no plans to expand it to mirror an RL model or anything close to that i.e. Premier League.
There are tentative plans to expand the NFL outside the US with new teams though, such has been the success of the business model.
(And even with a big collegiate base the professional game took a long time to grow from it's corner using the more traditional models)
