It would be interesting to take this data and build an app around it for fantasy football. If you have all the tendencies, and how players like your player have played against certain teams, you could make better guesses on who to play.
I did something like that for an AI class in college. We used FuzzyCLIPS to write an expert system for drafting fantasy football teams. A ruby script pulled the CSV data from some other site that had the previous three years of NFL data, and then converted the CSV to fact files which the system then read in.
When all was said and done it worked, but made some pretty crappy draft picks! I should find that code....
