The most significant addition to Scientific Football 2006 (now available for pre-order at www.TheFootballScientist.com) is the introduction of run-blocking metrics. I frequently receive the following two questions regarding run blocking metrics:
1. Can you explain your tracking system for run blocking?
2. Which linemen grade out the best in your system?
When I created the tracking system, I decided to base it around a yards-per-attempt metric. Yards per attempt is the central metric I use to track every other player on the field, so it only makes sense to track offensive linemen in a similar fashion.
