If NFL Week 1 seemed like one of the worst in memory for clutch field-goal kicking, that’s because it was one of the worst in memory.

The Cincinnati Bengals, Pittsburgh Steelers and Indianapolis Colts all missed tries with the score tied in overtime. The Atlanta Falcons, Tennessee Titans and Denver Broncos all missed late fourth-quarter kicks while trailing by one point.

The fallout was immediate as the Colts cut kicker Rodrigo Blankenship, who also sent two late kickoffs out of bounds during a 20-20 tie with the Houston Texans. The Colts had been favored by seven.

It was the sort of opening weekend that reminds fans, executives, coaches and players that the exhilaration of impending victory can quickly become the misery of unexpected defeat. How bad was it for clutch kicking in Week 1? Worse than any regular-season week since at least 2000.

What the heck happened? And what does it mean?

Longtime former NFL special-teams coach Mike Westhoff, reached Thursday while promoting his recently released memoir “Figure It Out: My Thirty-Two-Year Journey While Revolutionizing Pro Football’s Special Teams,” thinks he has a pretty good idea.

First, let’s look at the numbers.

The table below reveals details for the six missed tying or go-ahead field-goal attempts in the final two minutes of regulation or at any point in overtime for Week 1. The six misses in those situations were the most for any week since 2000, according to TruMedia, which has data since then.
