A rapidly crystallizing NFL playoff picture could gain several degrees more clarity after Sunday's schedule is complete.

Week 16 of the NFL season began Thursday night with a wild overtime game between the LA Rams and Seattle Seahawks. On Saturday, there were two games. There will be a Sunday night and a Monday night game. The Sunday night game on NBC will be Patriots-Ravens. On Monday on ABC and ESPN is 49ers-Colts.

The Steelers faced a simple task to seal the AFC North title in Week 17. But Pittsburgh's stumble could portend an ugly end to the season.
