It's amazing how different the numbers look when you compare >15 vs >20 yards. For attempts over 20 they're close, but over 15 yards they're miles apart.
I looked at deep pass numbers pretty closely during the 2010 season. I'm just going off memory, but from what I remember the numbers changed fairly dramatically from season to season for a number of QBs. I figured it was due to "parity" and the myriad of other variables involved. There were some that were relatively consistent.
The largest factor in the disparity is sample size, IMO.
