Denver went 14-3 last season, and the instinct is to hand them a championship-contender badge and move on. But every record deserves a second look, and this one is interesting. The Broncos' +90 point differential — applied to our fitted points-per-win formula — projects to 11 structural wins. They actually won 14. That three-game luck delta is the gap between what they earned on a play-by-play basis and what the scoreboard handed them, and it's the most important number in this piece.
A lot of that gap lives in the one-score column. Denver went 11-2 in games decided by eight points or fewer. That's a remarkable record, and it reflects real things — situational discipline, good moments from the quarterback, a defense that doesn't flinch late. But it also reflects variance. Coin flips don't always land the same way twice, and an 11-2 mark in close games is the kind of thing that tends to drift back toward the middle. The structural read isn't that Denver was lucky, exactly. It's that a genuinely good team won some tight ones that could have gone either way, and next year the math won't spot them three wins in advance.
