I don't know how this one is going to shake out, but before you get too excited remember that the Jags are averaging 19 rushes per game. That's 31st out of 32 teams. You can knock the efficiency of their individual backs, but their lack of production in the running game has also been a function of a lack of commitment to the run. Think about their most recent game. Rookie starter at QB. Close game. And yet their RBs had just 12 carries compared with 36 pass attempts for Bortles.
Unless you have Andrew Luck at QB, that's borderline suicidal coaching. Most teams that have actually been successful with a rookie QB (i.e. Roethlisberger, Newton, Wilson, Griffin) put the training wheels on those guys and limited their passing attempts to near the bare minimum. The Jags are doing the exact opposite. In two full starts, Bortles has 37 and 36 pass attempts. That's 36.5 attempts per game, which will be one of the top 6-7 averages in the league if it holds.
I would say they'll wise up and lean more heavily on the ground game in future weeks, but so far this season they've seemed pretty clueless.
