The validity of the analytical methods used here is highly, highly questionable. Never do they establish a link between their methodology and winning - you have to demonstrate that there's a correlation between your scoring and the probability of winning. They certainly don't at all. I wouldn't use this data.

Use ESPN's QBR, or PFF's DVOA, or Football Outsiders, or some of the other strong analytical groups that actually have pages describing how their methodology is connected to win probability.

ESPN's QBR is by far the strongest.
