I did a quick correlation calc between TOP and Offensive ypp/ypg, and Defensive ypp/ypg.

I ran this for four years' worth of data (2006-09).

It really looks like better defenses (by these measures) are much more strongly correlated to TOP than better offenses. (In the case of Yards Per Game, the difference is pretty stark, I think).

TOP Correlation to Yards Per Play
0.078 Offense YPP
0.120 Defense YPP (+.042 better correlation)

TOP Correlation to Yards Per Game
0.138 Offense YPG
0.354 Defense YPG (+.216 better correlation)

You guys can check my math; I might be all wet on this or I forgot something significant. I threw this together in about 20 minutes, but the results surprised me. I figured it would be a lot closer to even.

This seems to show us that defense is a stronger determinant of a team's TOP than offense.
