They should play 3 pre season games and have a 17 game regular season with the extra one being at a neutral site.
That way the owners will still get the revenue and the NFL will get more exposure in non NFL markets.
I think this is a win-win situation for everyone. The owners get their revenue, the NFL will get more exposure and turn more people onto the game. The players play more meaningful games and they should get paid for the extra game. There will have to be a tweak to the roster limit and IR concerns, but I am sure that the people working for the NFL and the NFLPA will figure this out.
