QBs in Focus: Mike Glennon

qb-month-glennonThough we certainly miss football during the offseason, it’s always a good time to take a step back and analyze our plethora of data.

We’re often so busy grading and collecting data during the season that we’re unable to put a lot of the information to good use. With that said, we’ve decided to declare June as “QB Month” as we break down NFL quarterbacks every which way.

We’re going to examine quarterbacks from a number of situations before looking at each of them individually. The grades and numbers should reveal each quarterback’s strengths and weaknesses from the 2013 season.

As we go through this series, it’s important to understand the relationship between QB Rating (NFL’s version) and PFF Grade.

While QB Rating is obviously supposed to be a QB statistic, it’s actually a better gauge of what the entire offense did in a given situation. This is the type of information that is actually extremely valuable to our NFL team customers as their game planning efforts must go towards stopping an entire passing offense, not just the quarterback.

If the quarterback throws an easy dump off pass to the RB who then weaves through the defense for the touchdown, it’s certainly not a great indicator of quarterbacking skill as it is the running back and defense accounting for the majority of the work on the play. Of course the QB Rating will look quite shiny in that situation.

On the other hand, PFF Grade is a good indicator of how well the quarterback actually performed in a given situation. Whether they throw an accurate pass that was dropped, or perhaps an inaccurate one that should have been intercepted and the defense dropped, the PFF grade will account for those situations with a positive and a negative grade respectively while QB Rating will simply reflect the 0-for-1 passing.

It’s important to distinguish between QB Rating and PFF grade, though there’s a good chance they’ll match up in most situations.

After taking a look at the entire league in various situations, it’s time to break down each quarterback individually.

    Definitely room to improve, but he did well IMO considering the situation he was thrust into last year
