Teams sitting at home in January can rejoice in one NFL truth while regretting another. They can rejoice in the fact that the NFL's extreme parity -- more than 20 teams were in the playoff mix in the final weeks of the regular season -- facilitates quick rebuilds. The Cincinnati Bengals, for example, just executed a six-game turnaround, going from four wins and a top-five draft pick to 10 wins and a division title. But the Bengals have Joe Burrow, which brings us to the regret: Many of the teams in the bottom third of the standings don't have a steady quarterback option. Most also need offensive line improvements. Bad protection coupled with indecision in the pocket breeds losing.
