That's your Lions season: spontaneous evolution meets tragic regression, at just the right time.


And just for your own personal use, since you're probably wondering, here's the explanation of what the Aggressiveness Index actually is:

Aggressiveness Index numbers center around 1.0 and generally describe how much more (or less) likely each coach is to go for it on fourth down compared to his peers; for example, a coach with 1.20 AI is roughly 20 percent more likely to go for it than an average coach in equivalent situations. The Aggressiveness Index excludes obvious catch-up situations: third quarter, trailing by 15 or more points; fourth quarter, trailing by nine or more points; and in the last five minutes of the game, trailing by any amount. AI was expanded two years ago to include plays when the offense is on its own side of the field, excluding those obvious catch-up situations. A slightly newer version of AI we are using now also adjusts to judge coaches on all fourth-and-short opportunities, even when the play doesn't actually record as fourth-and-short because of one of those bogus delay of game penalties that moves the punter back five yards.


The overall leader on the AI was Sean Payton, whose Saints had a low number of qualifying opportunities (81 to Caldwell's 107) but had the fifth-highest overall AI rating since 1989.

The rest of the ratings are over at Football Outsiders.
