We all know this last preseason game is a total waste, and a lot of people think 18wk schedule is too much, so I propose to add it on to the regular season like this...
After 16 games there is always a bunch of teams tied for a wildcard spot, so why not take the four top conf teams who are not division winners play against each other, the four division winners would also play each other to keep things honest and the rest of the teams just filling out the schedule. Also think it would be great to see them as inter conference games too. The wild card teams would be undisputed and the division winners would have a chance to improve their conference rank for playoff seeding.
