Who cares if you win a conference title if you're not the last SEC team standing in the playoff?
So what, you get an automatic bye by not playing in the conference title game.
But WE aren't competitors. We're fans. I already noted how the interests and mentality of players differ from their coaches and fans. Reduced depth and a longer season puts a premium on keeping people healthy. This is analogous to war: you want your soldiers (players) prepared to defeat anyone, anywhere, anytime. But as generals (coaches) and civilians (fans), we shouldn't want to send them into harm's way frivolously when it doesn't matter. Winning a war sometimes requires avoiding fighting every potential enemy and every possible battle. Conserving resources and selecting your battles wisely is crucial.
Not necessarily. After a long season, players are playing impaired and more and more starters are missing snaps. You'll see greater parity in the playoff, I assure you. The health and stamina of starters will matter more in the playoff than how talented each starting roster was at, say, Week 4.
