Sam Bradford, and Ranking Quarterbacks by Yards per Completion

Bradford looks to check down.

As a rookie, Sam Bradford ranked last in the league in yards per completion. That year, he averaged 9.92 YPC, 1.61 yards per completion lower than the league average of 11.53. In his second and third years — 2011 and 2012 — Bradford was a little better in that metric, but he still finished 0.65 and 0.34 yards per completion below league average in those seasons. So far in 2013, Bradford has earned his reputation as a checkdown artist: with a 10.21 YPC average, he’s averaged 1.43 fewer yards per completion than the average quarterback.

If you take a weighted average (based on his number of completions in each season), Bradford has been 0.98 yards per completion below league average over the course of his 980 career completed passes. In August, I noted that the Rams have experienced constant turnover at offensive coordinator and wide receiver since Bradford entered the league. This year, with Tavon Austin, Jared Cook, and developing talents like Chris Givens, expectations were high for Bradford. So far, we’ve seen more of the same from Bradford, which means lots of checkdowns and few big plays.

For his career, Bradford has averaged just 10.68 yards per completion. The table below shows the 164 quarterbacks since 1950 to complete at least 850 passes. The far right column represents the difference between each quarterback’s career yards per completion average minus the league average (calculated on a weighted-average basis for each quarterback based on his number of completions in each season) rate. As it turns out, Bradford ranks in the “top five” when it comes to the worst era-adjusted yards per completion averages.

Ed Brown, who played first with Harlon Hill and later Buddy Dial, comes in as the biggest deep thrower of the last 64 years. A pair of AFL greats, Daryle Lamonica and Joe Namath, also make the top five in terms of yards per completion over average. Among active quarterbacks, Ben Roethlisberger (1.02), Michael Vick (1.01), Aaron Rodgers (0.80), Philip Rivers (0.73), and Tony Romo (0.62) are the top five active quarterbacks in YPC over average, while Bradford, Alex Smith (-0.54), Jason Campbell (-0.4), Chad Henne (-0.25), and Matt Ryan (-0.17) come in the bottom five.

Yards per completion is not the best way to grade a quarterback, or even a good one. Great quarterbacks like Joe Montana and Fran Tarkenton have low yards per completion averages, and the presence of Y.A. Tittle on the list makes sense in light of this post. But the issue with Bradford is his low YPC is paired with an unimpressive 58.3$ completion rate, and he’s been below league-average in completion percentage every year of his career. I agree with Jason Lisk — it may be time to give up on Sam Bradford, pending his performance over the final twelve games of the year.
