The Bills have forced two three and outs and a four and out. Sure the 4th down play inside the 5 was a horrible mistake by Seattle but the Bills had held on 3 downs before that.
It is the Bills defensive mantra. Never give it up and make them play one more play. Anything can happen. Played three tough downs to get them into 4th and goal from the 3. Then they got a bit of luck.
