Video: Peyton, Eli Manning, Matt Ryan React to Saquon's Drop, Kirk Cousins' GW Drive

Peyton Manning and Eli Manning went through it on the ManningCast broadcast as Philadelphia Eagles running back Saquon Barkley dropped a pass that would've resulted in a pivotal first down in Monday's 22-21 loss to the Atlanta Falcons.

Peyton got up from his chair as Eli went full "surrender cobra" as the ball fell to the turf. Former Falcons star Matt Ryan, on the other hand, seemed to breathe a sigh of relief.

The three retired quarterbacks also provided insight throughout Atlanta's game-winning drive, and Peyton's competitive juices were flowing as Atlanta's Kirk Cousins marched the offense down the field without any timeouts.

Barkley had another strong performance in his second game with Philly. He ran for 95 yards on 22 carries and caught four passes for 21 yards. The drop is the one thing people will remember, though.

"I let my team down today," he told reporters. "I shouldn't have put the defense in that position. If I make the catch, the game is over."

It was a much different story on the other sideline.

The Falcons' comeback changed the conversation around Cousins in a big way. The four-time Pro Bowler simply didn't look to be 100 percent in Week 1, his first start back from his torn Achilles, and Atlanta's offense couldn't get much going in the first half.

After halftime, Cousins flipped a switch.

It's too early to call this a season-defining win or a turning point for the Falcons. Their next three games are against the Kansas City Chiefs, New Orleans Saints and Tampa Bay Buccaneers, and that stretch will offer a much better barometer for how Atlanta's campaign will unfold.

In terms of Monday night's matchup, the ManningCast offered a good representation of how neutral observers were reacting to the late swings in momentum.
