PHILADELPHIA (CBS) — The picture began to look clearer. It started to take form almost two months into the season. The Eagles looked like they wiped out the touches of messiness, and it appeared the 2018 Eagles had finally arrived.

They did — at least for three quarters.

Then the Eagles did something historic. They blew a 17-point fourth-quarter lead and Carson Wentz went to pieces in the final minute of a 21-17 loss to the visiting Carolina Panthers, who scored three successive touchdowns in the fourth quarter on a brisk Sunday at Lincoln Financial Field.

The Eagles drop to 3-4, while Carolina improved to 4-2 and may have helped themselves down the line in the playoff picture — if the Eagles even make the playoffs.

With 31 seconds to play, and the Eagles at the Carolina 14, Wentz went numb — after almost throwing an interception two plays earlier — and was strip-sacked by Kyle Love and that was it.

It wasted an effort by Wentz, who had at one time completed 15-straight passes and finished 30-for-37 for 310 yards and two TDs. Tight ends Zach Ertz and Dallas Goedert combined to catch 13 passes for 181 yards and a touchdown. Alshon Jeffery caught seven passes for 88 yards and a touchdown.

Defensively, the Eagles had shut down Cam Newton and what looked like a predictable Panthers’ offense. In the first half, the Eagles held Newton and the Panthers to five net yards passing, thanks to two Eagles’ sacks for minus-19 yards. Entering the game, the Panthers had given up only eight sacks all season, yet surrendered two in the first half against the Eagles.

Then the fourth quarter began, and Carolina scored on successive drives of 80, 87 and 69 yards — and the Eagles had no answers.

The rest of the Eagles’ schedule now suddenly looks daunting. Big dates come at New Orleans on Nov. 18 and at the Los Angeles Rams on Dec. 16. Other than that, the Eagles have five dates against their NFC East rivals, who don’t appear that frightening at all, and games against listing Jacksonville, which pulled Blake Bortles against Houston, and the Texans in late December.

It took a little time, but the Eagles team everyone expected to see finally arrived.

For three quarters.

The Ugly
