Broncos bettors were sitting pretty mid-way through the fourth quarter of last night's "Monday Night Football game." 

With Denver leading 23-13, bettors who either took the Denver moneyline or the 3.5 points started counting their winnings as the Chiefs looked destined for their first loss of the season. 

And then something changed.

The Chiefs offense started clicking on a 12-play, 75-yard drive, taking nearly six-and-a-half minutes off the clock, to make the score 23-20 with 6:27 left.

Then on the Chiefs' final, and ultimately game-winning, drive, they converted on a third-and-7 from Denver’s 46-yard line with just over two minutes left on the clock: 35-yard pass from Patrick Mahomes to Demetrius Harris to put the Chiefs in scoring position. Only the play should have never counted. 

The play clock was at zero when the ball was snapped, and KC went on to score the go-ahead and game-winning touchdown just three plays later.

There was still hope for Broncos fans and bettors alike. With less than a minute on the clock, Denver was driving and had a third-and-10 from the KC 28-yard line. Case Keenum dropped back and had Demaryius Thomas wide open in the right corner of the end zone. The ball sailed on a pass that I'm sure Keenum would like a do-over on. Mahomes reaction says it all.

Fourth down then came and went on a failed hook and ladder, and the Chiefs kneeled out the clock with a 27-23 win -- covering the 3.5-point spread.
