PHILADELPHIA — The look was strange: Andy Reid in all red on the visitors’ sideline.Reid’s homecoming was a smashing success for the new Kansas City coach thanks to a dynamic defense that forced five turnovers and sacked a harried Michael Vick six times in the Chiefs’ 26-16 victory Thursday night. Vick even limped off with 1:07 to go after the final sack and fumble, but stayed around to hug Reid after the final play — just after Donnie Avery gave Reid a Gatorade shower on the sideline. Kansas City (3-0) has won one more game already than it did in 2012 — when it earned the first overall draft pick, then hired Reid days after he was fired on the heels of Philly’s 4-12 finish. It was Reid’s defense and special teams that set the tone and put his team ahead early. The Chiefs forced four first-half turnovers and Houston had three of their four sacks. He had another half-sack to start the second half, off a bad snap to Vick, and the last one when he forced Vick to fumble with 1:34 remaining. Houston has 7 1/2 sacks in three games. Damaris Johnson’s muffed punt return gave Kansas City the ball at the Eagles 8, leading to Ryan Succop’s 33-yard field goal for a quick 3-0 lead. Derrick Johnson then deflected Vick’s ill-advised throw into the flat and Eric Berry picked it off, going 38 yards.There would be more mistakes as Philadelphia (1-2) lost its eighth straight home game. Down 10-0, Vick got the Eagles’ offense going with the longest run of his 12-year career. He burst up the middle and sped 61 yards. Two plays later, he hit Jason Avant for a 22-yard score. That three-play, 87-yard spurt epitomized the fast-paced offense coach Chip Kelly brought from Oregon. But Kelly got cute, going for a 2-point conversion on tight end Zach Ertz’s run that failed. The takeaways kept the Chiefs in front.
