We are past the quarter point in the season, giving us more data to pore over. How much can we look at when it comes to offensive lines? While pancake blocks are statistics best left for Madden, each lineman's ability to keep his quarterback clean is as good as it gets.
A few weeks ago, I created a metric based on how many quarterback pressures—sacks, hits or hurries—they have given up to measure the quality of play among linemen, specifically as it relates to pass blocking. Here is an explanation of the metric:
Not all pressures are created equal, however. A lineman might give up plenty of hurries, but if he keeps his quarterback clean he will get more credit than one who puts his own quarterback on his back.
As such, the metric is weighted more heavily toward hits and sacks, and it is based on opportunity—if Player A has 30 fewer pass-blocking opportunities than Player B, Player A is going to have his score more adversely affected by a single sack than Player B.
The lower the score, the better. Anything below 1.0 is elite. Different positions offer different scoring ranges—tackles are going to give up more pressures as a whole than centers—so the range of poor scores varies.
It is important to note these rankings are strictly based on statistics. There is no subjectivity here, just data.
