Expanding the playoffs is silly.
What makes football (and baseball) better than basketball and hockey is that not every team makes the playoffs, which makes the games that much more important.

to 18, or even 20 games.
Wipe out the awful empty week before the Super Bowl, wipe out the bye week, and shorten the preseason by a game or two, and you don't even have to lengthen the season.
And think of all the conversations the sportsmedia can have about when coaches choose to rest certain players for a series or a game mid-season.
