Three big NFL Week 12 comeback wins: Cowboys, Lions, Chiefs - ESPN

It was dangerous to have a big lead in the second half of Sunday's Week 12 games. Sure, the Packers and Rams had no trouble and ended up with comfortable wins. But other teams that took big leads had to fight to hold on for wins. The Falcons allowed the Saints to march up and down the field in the second half, though New Orleans fell apart near the goal line. The Seahawks let the Titans get within one score after a series of late touchdowns. And the Bears needed two stops against the Steelers at midfield to hold onto yet another narrow victory in Chicago.

Three teams, though, could not hold on. The Giants fell apart with a big lead in the second half yet again, as the Lions came back from a 10-point deficit in the fourth quarter to win in overtime. The Eagles got out to a 21-0 start on the Cowboys and spent the rest of the game seemingly hanging on in desperation, with Dallas eventually breaking through for a game-winning field goal as time expired. And the Colts, looking for a statement win over the Chiefs, led 20-9 with the ball in the fourth quarter but somehow still managed to let Kansas City win.
