I like to mess around with the awesome suite of RotoViz Apps, in particular the AYA App is great to see how efficient a quarterback is throwing to all his receiving options. While going through all the big-name QBs I found lots of receivers that were either more or less efficient than I thought they would be. This led me to take a deeper look at how a receiver’s efficiency versus that of his teammates (what I’m calling Relative AYA) affects future performance. I looked at it a few different ways, and was eventually blown away by Relative AYA’s implications for rookie wide receivers.
