More football, in most cases, is always good. More playoff games definitely are good.

But here’s one thing that may not be so good: The official expansion of the field from 12 teams to 14 places a gigantic premium on earning the top seed in each conference.

The No. 1 seeds become the only teams to get a weekend off. Which means that the No. 2 seeds — typically, the biggest threat to the No. 1 seeds — will have to play another game, putting the No. 2 seeds at risk of losing that game and also at risk of getting someone injured.
