Week 13 in the NFL is well underway with four games already under our belts over the Thanksgiving and Black Friday holiday. Now, it's time to heat up the leftovers and gear up for a jam-packed Sunday slate where we have a number of key matchups with major playoff implications.

Detroit is the best team in the NFL, a covering machine, and it has a +177 point differential, which is 71 higher than the next team (Eagles). Of its last eight games (8-0), only two of them have come by single digits. The Bears and Lions are tied for third in the NFL in turnover margin (+9) and weirdly, Chicago is 4-7.

The Colts got spanked by the Detroit Lions last week and looked nothing like the team that pulled off a big win the week before against the struggling New York Jets. The Patriots also got spanked last week in a puzzling showing against the Miami Dolphins, looking nothing like the team that had been playing respectable football the past few weeks.
