Sunday Night Football at Lumen Field began with the raising of the 12th Man flag but it wasn't Seattle Seahawks fans making the most noise. Green Bay Packers fans stole the show.
The Seahawks didn't just suffer the indignity of trailing 20-3 at halftime. They also had to listen as Packers fans chanted "Go Pack Go!" so loud it was audible on the NBC broadcast.
From the get-go, it was clear that Packers fans had traveled in droves. That or there is a sizable Green Bay enclave in the Pacific Northwest.
Social media marveled at the famed 12s of Seattle being shown up in their home stadium. It's just not often that happens, especially for a Seahawks team leading the division.
Seahawks fans weren't loving it, that's for sure.
