Before the start of the NFL season, we brought you the Patriots Play Predictor, which was a database of all the plays the offense ran in 2011 that could be filtered a number of ways.

Now, we've whipped up this year's version, and done the same for this week's opponent, the Buffalo Bills.

The first three weeks of plays for each team have been set into a database to display the Patriots tendencies and the personnel they've used based in situations set by the user. We'll be updating the Play Predictor with a new version for each opponent every Friday.
