One of my favorite "advanced" stats is wide receiver drop rate.

It's really fairly simple, taking the number of drops and dividing them by the number of targets a wide receiver receives. Unfortunately, most NFL stat places don't keep track of how many of those targets are catchable, and which are not, which is critical when looking at drop rate.

Fortunately, Pro Football Focus has kept track of that since 2008, making a drop rate that is extremely useful when comparing wide receivers.

After an extremely frustrating year for Colts wide receivers in terms of drops, I started playing with PFF's wide receiver numbers and decided to take a look back into the past five years and look at the Colts' numbers. The final product was fascinating, at least to me.
