It's been a week of whiplash for the Seattle Seahawks. They go from a convincing win over the NFC South-leading Falcons to just a dreadful Week 8 showing against the Bills.

And if you needed any idea of just how poorly the game went for the Seahawks, just look at the muffed punt that effectively iced the game for the Bills.

The Seahawks were looking to get the ball back down 21 with two minutes to go, but as cornerback and punt returner Dee Williams readied himself to field the punt, he slipped on the wet turf. He knew right away that he was in trouble, and we could hear it on the broadcast -- loud and clear. (Warning: Some strong language)

Yeah, it's never a good sign when a player yells that in the middle of a play. Williams learned the hard way that wet turf can be quite slippery.

Buffalo easily recovered the muffed punt and kneeled out the clock.
