After a dominant showing in the first half, the Seahawks defense cracked in the third quarter Sunday. It started with a Julio Jones touchdown. It got worse with another Matt Ryan touchdown pass, this time to Mohamed Sanu. It got even worse with Ryan's third touchdown of the quarter just 17 seconds left before the fourth quarter.

The Falcons turned a 14-point halftime deficit into a seven-point lead in 15 minutes.

And the Seahawks suddenly aren't having fun anymore. After Jones' touchdown, a visibly angry Richard Sherman let his emotions fly on the sidelines. According to The Seattle Times' Sheil Kapadia, Sherman "chucked his helmet" as he exited the field.

He was eventually restrained by his teammates.

Perhaps Sherman was upset with the Seahawks' coverage on the play, in which Jones lined up in the slot. As Sports Illustrated's Chris Burke pointed out, Sherman actually matched up with Jones before the ball was snapped. But when Ryan motioned another pass catcher to the outside, Sherman left Julio for the boundary.

And so, Jones shook free of Sherman before the ball was even snapped. He wound up with a wide-open catch before he coasted into the end zone. Below, you can see Sherman on the left sideline.

Credit Falcons offensive coordinator Kyle Shanahan for finding a way to scheme Jones open. And don't blame Sherman for showing his emotions on the sidelines. It's football. Yelling happens.
