http://espn.go.com/blog/afcsouth Ask me who the most aggressive coach in the AFC South is on fourth down, and Id unhesitatingly say Jack Del Rio. He goes for it, quite frankly, a bit too often. But according to Football Outsiders, he was actually the fourth-most aggressive coach in the division on fourth down. The computation for FO's Aggressiveness Index (AI) is a little more complicated than just giving the overall rate of going for it on fourth downs: "Instead, the head coach's record in different 'going for it' situations is compared to the league average, with the numbers weighted by the number of opportunities the coach had in each situation." And under that formula, the divisions coaches rated like this in AI: * Eighth Gary Kubiak * 12th Jeff Fisher * 14th -- Jim Caldwell * 20th Del Rio Even so, I think Del Rio should give into his gut feeling a bit less. Caldwell, given his offense's strength and defensive weakness, could be more aggressive. (Nate Dunlevy certainly thinks so.) I found this interesting. i would find myself getting so mad last season cause Kubiak would punt, our kick a FG when i knew we could get the 2 inches we needed. i don't see how he's 8th on the list.
