So here's what I did, as the crazy stat tinkerer that I am: I started with the stat lines for all QBs who threw a qualifying amount of passes this season (that's 224 according to the NFL). I am counting post-season stats as well. Then, what I do is I determine the player who had the most attempts among the sample, in this case it is Tom Brady with 731 attempts.
I then use that as the baseline, so I will adjust every stat up to 731 attempts. (In other words, Joe Flacco threw the ball 657 times, so I will multiply all of his stats by (731/657) to determine what he was on track for if he threw the ball that many times.
I've thrown out completion percentage, because frankly we're talking about raw numbers here in terms of yards, touchdowns, and interceptions, where every player on the list is now assumed to have thrown the ball the same number of times. Personally, I don't care if one guy got to 5000 yards by completing 55% and another guy by completing 65% of his passes, as long as they both passed it the same number of times, those yards count equally towards his efficiency for me; the only difference is a clear scheme difference between dink & dunk and big play, but the net result is the same.
So you can see how many yards, touchdowns, and interceptions each qualifying QB would have thrown for if they had the same number of attempts as Tom Brady. You can also see the average. And I've got a couple of other things in each line as well, such as the difference over average (how many more or less yards, touchdowns, and interceptions), the adjusted yards stat (which is calculated as yards + (20 * touchdowns) - (45 * interceptions), the touchdown/interception ratio, and a new item I've called "Points", which I'll address next.
Points is what I've used to rank the players, first of all. But what are points? It's a new measuring stick I came up with for this analysis. Each player in this scenario is assumed to have thrown the ball the same number of times. So what I did was I took the average yards, touchdowns, and interceptions, and I divide each player's individual stats by those averages. The formula is ((Yards/AvgYards) + (TDs/AvgTDs) - (INTs/AvgINTs)) * 100.
100 points is always exactly average, and there is no maximum or minimum (points can even be negative if you throw far more interceptions than average versus your numbers in yards + TDs).
So on with the show:

The difference between Flacco and Brady, for instance, is:
1. Tom Brady: 5491 Yards, 38 TD, 10 INT = 5801 Adjusted Yards, 3.8:1 TD/INT Ratio
2. Joe Flacco: 5515 Yards, 37 TD, 11 INT = 5749 Adjusted Yards, 3.3:1 TD/INT Ratio
Flacco compared to Brady would have: +24 Yards, -1 TD, +1 INT
And between Flacco and Ryan (adjusted for 692 attempts, which was Matt Ryan's figure, the most between the two):
1. Joe Flacco: 5221 Yards, 35 TD, 11 INT = 5442 Adjusted Yards, 3.3:1 TD/INT Ratio
2. Matt Ryan: 5365 Yards, 38 TD, 17 INT = 5360 Adjusted Yards, 2.235:1 TD/INT Ratio
Flacco compared to Ryan would have: -144 Yards, -3 TD, -6 INT
He compares very, very favorably to both, as you can see.
Hey, if you want to see any specifics besides what I've shown, just let me know. I can compare just certain players at your request, I can compare different seasons or ranges of time, whatever you can think of just ask.
