The only thing certain in the NFL is that nothing is certain.
Week 6 was living proof of that.
After six weeks, the 1972 Dolphins can pop open the bubbly again, because the league's two remaining undefeated teams both fell in stunning fashion. In Cleveland, the San Francisco 49ers were beaten by a Cleveland Browns team starting P.J. Walker at quarterback. In New York, the Zach Wilson-led Jets rode a stellar defensive performance to an upset of the unbeaten Eagles.
There was nearly a third upset—the one-win New York Giants outplayed the Buffalo Bills for most of Sunday night's game before falling late.
