A lot of good teams just weirdly trying to 'game management' themselves through two-score leads and it coming back to bite them.
The Jags are another potentially sneaky-good team this season. They'll certainly feel now that the playoffs are possible.
Again - every single 'top' team in the league have clear issues right now, Chiefs included.
Just a word on the refs as well - there always seems to be particular weeks where we see a lot of iffy calls, particularly late in the game. Eagles on Sunday stopped that last Broncos drive 3 times but only one of them actually stuck because of two really questionable penalties...
