 The Guardian weighs in on American football playoffs:

The NFL’s bogus playoff seeding system penalizes the more deserving  by Doug Farrar

"The injustice of the NFL’s playoff seeding system rears its ugly head once again.

"Now that we know how the 2024 NFL playoffs are seeded from top to bottom, it’s time once again to complain about the league’s ugly secret: its system for awarding playoff position, and thus which teams will have postseason games at home or on the road, is seriously flawed.

"The primary culprit is the league’s insistence that every division winner gets at least one home game. That would be somewhat equitable if every division winner was above average, but the process of elimination tells us a different story."
