By HOWARD FENDRICHAP Pro Football Writer Even as the New England Patriots won a 10th game for the 15th consecutive season to move closer to yet another AFC East title and a No. 1 seed for the playoffs, a late hit to an opponent's head by Rob Gronkowski and a sideline spat involving Tom Brady made things interesting for the defending Super Bowl champs.

In case you missed it, here are the other top topics after the NFL season's 13th Sunday: THROW THE FLAG Nothing is going right for Andy Reid's Kansas City Chiefs, who have completely come undone after a 5-0 start, losing six of their past seven games to drop into a three-way tie atop the AFC West at 6-6 with the Los Angeles Chargers and Oakland Raiders. And during their 38-31 loss at the New York Jets, the Chiefs really
