Personally.. I know this sounds anti logical for a football nut like myself.. but I don't think I would like an additional two regular season games.
Why?
I think it will water down the importance of a single game.. more games equal less importance on any single game.
My opinion.. stay at 16 weeks.. cut the preseason down to 2 or 3 at the most and launch a developmental league for rookies and guys with say less than 3 years experience.
That would raise the talent level, allow football to be more of an annual sport and still accomplish raking in the coin for the owners. A 6 to 8 week summer league in the same venues with assistants coaching the teams
