Bills HC Sean McDermott: Loss to Chiefs 'comes down to execution'

The Buffalo Bills were 13 seconds away from earning what would've been a comeback playoff victory for the ages at the Kansas City Chiefs on Sunday night, but it wasn't to be for multiple reasons. 

Chiefs quarterback Patrick Mahomes shockingly guided his offense down the field for a game-tying field goal delivered as regulation expired and then produced a memorable touchdown-scoring drive on the only possession of the overtime period to propel the hosts to a dramatic 42-36 win. 

Bills head coach Sean McDermott made it clear during Tuesday's media availability this loss will stick with him for some time. 

"I watched it on video and I watched it over and over in my head a million times, in my stomach a million more," McDermott explained, according to Alaina Getzenberg of ESPN. "It's my livelihood and I'm super competitive as well. I want the best for our football team and this organization and our fans, quite honestly. So I'll continue to watch it in my mind and in my gut for years ... but when we get to where we're trying to get to, I believe that'll make it that much more enjoyable in that moment."

Some have wondered why McDermott and company elected against kicking the football short of the end zone to drain some clock with the Bills leading 36-33 and only 13 seconds left in the fourth quarter.

"It comes down to execution," McDermott said without directly mentioning any one call. "(It's) disappointing because we pride ourselves on detail. We pride ourselves on execution and being great in situational football. And we practiced that tirelessly here. I mean, nonstop. ... It's even more disappointing knowing that we prepare and practice those situations a ton here in Buffalo. That's where I come back to you gotta face it and we're not gonna run from it. I believe in that."

McDermott wouldn't comment on if placekicker Tyler Bass handled the game's most important kickoff as directed or if there was any miscommunication between the special teams unit and coaches before that noteworthy untimed touchback. As things stand today, that will probably go down as the most scrutinized kickoff of the postseason tournament.
