Your model is pretty pathetic. The dependent and independent variable seem irrelevant in the method they are being tested.

Common sense indicates the QB affects YAC

Slash-To be honest I try hard not to watch the Eagles. So I'll defer to your first hand experience.

The McNabb/Garcia issue is probably one where you need to document every play.

That's a good point about the bomb passes that get behind the defense, they have potential for a lot of YAC. But RBs all have a lot more YAC than WRs as a rule. My theory is that WRs get a lot of

I guess maybe another thing I would be curious about (wouldn't mind finding it out myself but not sure where to find these numbers) is the rac differences based on air yard differences.

For example the average Yac on a pass that is thrown 10 yards downfield vs. that of one thrown 20 yards. I guess things like the deep outs would have an affect here, with a strong armed QB as you

Actually just watching the games, the thing that changed when McNabb went out was the long ball. The Air yards were higher for Reggie Brown with McNabb than with Garcia (also the plays of 20+ and 40+ were higher), same with Donte Stallworth, Greg Lewis, Hank Baskett, LJ Smith, Westbrooks air yards went up slightly (from -.5 to 1.9 per catch. In the end with the receivers from what I saw in the

Slash-Since I made this post I've learned a lot about YAC. QBs that tend to check down a lot, or rely on RB screens/flares get lots of YAC. Those types of plays do not require a very skilled QB.

The QBs who don't get a lot of YAC are those with the stronger arms--Manning, Palmer, Romo, etc. They throw downfield passes and out routes near the sidelines that don't tend to generate YAC.

Another thing to consider is possibly the QB's arm strength. I had done a breakdown on the Eagles Rac with McNabb and with Garcia, and the differences were massive. someone had thought that Garcia was more accurate, thus the Rac should increase. But when looking at the breakdown, Donte Stallworth I believe was the only receiver with anywhere near a close RAC with both QB's. The rest had

I think a really useful angle to further investigate would be year-to-year correlations of YAC. Specifically:

1) Do certain receivers have consistently good YAC (e.g. TO)? My guess is yes.

2) Can we largely explain year-to-year correlations of a QB's YAC by what receivers they complete passes to? If you could create a model that shows that QBs have almost no year-to-year
