NFL expansion would be a huge mistake

The Math Just Works
The NFL right now is a thing of mathematical beauty—four teams per division, eight divisions in the league, with 32 teams playing 16 games each.
There is balance. Schedules work. No team or division has a built-in advantage, something the league—to its credit—has always strived to prevent.
When the league adopted its first scheduling matrix in 1978, which set matchups based on where teams finished in their divisions the previous seasons and called for a scheduled rotation of interconference play based on division assignments, the league prevented any potential scheduling mismatches.
Even with each conference having two five-team divisions and one four-team division, the NFL designed the schedules of those fifth-place teams in such a way that every team in the league played the same number of games against those last place teams—two.
But things got messy after the Cleveland Browns came back in 1999. That left the old AFC Central with six teams and a scheduling problem, because it now had to accommodate six teams having to play 10 divisional games, with no way to balance it.
Not coincidentally, at least one wild card in each of the three seasons the league played under that configuration, 1999-2001, came from the AFC Central.
