NFL Week 15 grades: Patriots get a 'D' for shocking loss to Raiders; Cowboys earn a 'C' for surprising setback

Here are the Week 15 grades for every team that played Sunday

After a wild Saturday that gave us the biggest comeback win in NFL history, the action on Sunday might have actually topped that. 

In Las Vegas, the Raiders beat the Patriots with one of the wildest walk-off plays ever: Chandler Jones snared a lateral on the game's final play and then proceeded to return it for a touchdown to give the Raiders an improbable 30-24 win over the Patriots. 

In Tampa Bay, Tom Brady blew the biggest lead of his career in a home game. The Buccaneers led the Bengals 17-0 in the first half, before suffering a total second-half meltdown in a 34-23 loss.
