Rapid Reaction: Chiefs 26, Eagles 16

PHILADELPHIA -- A few thoughts on the Philadelphia Eagles' 26-16 loss to the Kansas City Chiefs:

What it means: Chip Kelly’s offense can be stopped, and Michael Vick is still prone to the kind of mistakes and injuries that helped create a job opening for Kelly in the first place. Vick threw two interceptions, including one returned 38 yards for a touchdown by Chiefs safety Eric Berry. Vick was also sacked five times as Kansas City’s defense disrupted Kelly’s read-option offense. On his last play of the game, Vick fumbled the ball away after being sacked by Justin Houston, then limped off the field with an apparent ankle injury. The Eagles are 1-2 and, with a road game in Denver next on their schedule, staring 1-3 right in the face.

Stock watch: Falling: Chip Kelly. With so much attention on the return of Andy Reid, Kelly’s predecessor, the first-year coach could have made a bold statement about the Eagles’ new world order. Instead, Kelly has lost his first two home games and seen his offense solved by an NFL defensive coordinator. Four days after admitting he didn’t manage the clock properly in the final minutes of a 33-30 loss to San Diego, Kelly has even more profound questions about the long-term effectiveness of his scheme.

Reid and react: The big topic of conversation in Philadelphia all week was how fans would, and should, respond to Reid in his first game here as a visiting head coach. There was similar debate about Donovan McNabb, the franchise quarterback of the 2000s, whose No. 5 was retired in a halftime ceremony. Both men were cheered enthusiastically. The Eagles flashed a thank you message to Reid as he walked onto the field, triggering a standing ovation, and McNabb was cheered as fireworks exploded over the stadium.

Shady, scary: LeSean McCoy, the NFL’s leading rusher, grabbed his lower leg and howled in pain after being tackled late in the first half. McCoy left the field to chants of his nickname, "Shady, Shady," and received X-rays. He returned with the team after halftime, but backup Bryce Brown began the third quarter in the backfield. McCoy returned with a vengeance, however. He broke a 30-yard run on his first touch after missing a series. In the fourth quarter, his 41-yard touchdown run got the Eagles within striking distance of the Chiefs at 23-16. McCoy finished with 158 yards on 20 carries.

What’s next: After playing three games in 11 days, the Eagles get 10 days to recover, regroup and prepare for their next game. There is much to do. The pass defense was better Thursday than it was against San Diego on Sunday, but still looks like a smorgasbord for Peyton Manning. And Kelly has to find a way to tune up his offense and get Vick back to where he was in his first two, relatively mistake-free starts.
