It didn't take too long for just about every team to take a loss this regular season. Just five weeks in, we're down to two teams chasing the 1972 Miami Dolphins. The Kansas City Chiefs and Minnesota Vikings are the two 5-0 teams left in the NFL. When we wonder which team will be the last undefeated standing, Minnesota is probably the better answer.
If the Vikings clear one upcoming obstacle, it's feasible they could be deep into November without a loss. After a Week 6 bye, the Vikings host the Detroit Lions. That will be a tough challenge that could ultimately decide who wins the NFC North.
