Over the last couple of days, I’ve been looking at measuring the age of a team’s passing attack. On Friday, I noted that the Jaguars had the 2nd youngest passing offense in the NFL behind only Tampa Bay. And yesterday, I measured the youngest passing offenses in football history, with Jacksonville checking in at #20.

The Jaguars threw for 4,428 gross passing yards last season (or, 8,856 combined passing/receiving yards), though, so that makes them a bit more of an outlier. The table below shows all teams with at least 8,500 combined passing/receiving yards, and ranks them in ascending order based on average age:

For Jaguars fans, I would say this qualifies as some pretty good news. We should acknowledge that it is probably misleading to just lump Jacksonville with the best passing teams without recognizing that the Jaguars threw 607 passes last year; that’s a lot of pass attempts, and it’s a huge number compared to the average team over the course of NFL history. So it would be easier (and, in some cases, a lot easier) for the Jaguars to throw for 4,250 yards than it would be for other teams throughout history. This is obviously going to be biased toward modern teams. That said, look at the other top five teams:

• The 1994 Patriots had a 22-year-old Drew Bledsoe, along with Ben Coates (25), Vincent Brisby (23), and Michael Timpson (27), along with other young skill position players. In two years, the Patriots would be in the Super Bowl.

• The ’84 Dolphins were one of the greatest passing teams of all time, but also a really young one. Dan Marino was just 23 years old, while Mark Duper was 25 and Mark Clayton was only 23.

• The ’13 Bengals had Andy Dalton (26), A.J. Green (25), Marvin Jones (23), Giovani Bernard (22), Hermaine Gresham (25), Mohamed Sanu (24), and Tyler Eifert (23). That was an incredible collection of young offensive skill position talent on one team, although it hasn’t yet resulted in a playoff win for Cincinnati.

• The 2011 Lions had Matt Stafford (23), Calvin Johnson (26), Brandon Pettigrew (26), and Titus Young (22).

From an efficiency standpoint, Bortles and the Jaguars passing attack was far from great last year; he was still slightly below league average in ANY/A, and ranked 27th in QBR. He had an unusual season, ranking 2nd in touchdowns, 1st in interceptions, and obliterating the NFL record for touchdown passes while trailing.
