Last night, Andy Dalton was not very good. completed 10 of 33 passes for 86 yards, while throwing 0 touchdowns and 3 interceptions. Add in his two sacks for 14 yards, and Dalton averaged -1.80 ANY/A. That’s terrible, of course, but how bad does that measure historically? Let’s use the same methodology we did when calculating how good Ben Roethlisberger was against the Colts. Against every other passer this year, the Browns had allowed 5.58 ANY/A to opposing players. As a result, Dalton finished 7.38 ANY/A below expectation.

Over the course of his 35 dropbacks, that means Dalton provided -258 adjusted net yards of value relative to expectation. That’s bad — really bad — but it only ranks as the 83rd worst performance since the merger. The table below shows the 150 worst games since 1970, although for 2014, I have only included Dalton’s game (so Geno Smith and his bad performances could make the list, but I didn’t have time to calculate — feel free to do so in the comments!).

Feel better, Bengals fans?
