Historical Football Chart

How about this chart to look at GT's history in football. As much as I can figure out, here is the legend:

PFPG (Points For per game = points we scored?)
PAPG (Points Against per game = points allowed?)

The green and red lines tracks these points. So you can see in 1990 that the PFPG was much higher than the PAPG, and of course we won the whole shooting match that year.

The blue line is out winning %. What you can really see from that line is that this program has really been cyclical the last 20 years. Of course, like that's not something we didn't already know.
