Dave Berri just posted his final NFL quarterback ratings for the 2009 season, which are always interesting.

Schaub moved up into the top quarter of NFL QBís, but he has a ways to go before he is playing on the level that Rivers and Brees played on this past season. Interestingly, there is a big drop off in production between Schaub at no. 8 to  Roethlisberger at no. 9.

Except for the truly great ones, QBís are notoriously inconsistent from season to season, especially in comparison to basketball players and hitters in baseball. For example, Favre went from the 27th ranked QB last season to no. 4 this past season! Thatís due primarily to the more complementary nature of football. Stated another way, itís hard to be a productive QB when laying on oneís back or running for oneís life.

Thus, statistics really donít tell us much about NFL QBís (except when that QB is as bad as David Carr) other than the fact that a particular QB performed well this season does not necessarily mean that he will do so again next season.

Are you listening, Chron cheerleaders?
