Baseball Prospectus, FanGraphs and all the baseball stat sites can find the raw data they need relatively easily. The formulas they put them in -- not as easy. Still, the data is there.

Football Outsiders, on the other hand, has to do some extra work to gather a lot of the raw statistics they use on their site and in their annual book. A lot of this work is done by game charters who track things during the game. At the end of the season, all of this information is calculated and we learn a few things about each team we may not have known before; though, sometimes we had a pretty good idea.

What FO’s game charters told us about last season is that the Bears didn’t break any tackles. This is just stats confirming what was already suspected; if you consider the way people felt about two of the Bears most utilized players -- Greg Olsen and Matt Forte -- this is far from surprising.

Based on the numbers, the Bears had a play with at least one broken tackle only 3.5% of the time. Only the Packers’ had a smaller percentage of plays with a broken tackle.

Oh, and in case you were wondering, on defense the Bears were middle of the road (16th in the NFL) in terms of making tackles. Not that this is any indication of success: the No. 1 team in not allowing broken tackles was the St. Louis Rams, an otherwise terrible defense.
