Sam vs The Record Books: Week 15

Sam Darnold’s best game of the year last Sunday means things are looking up in our season long tracking of Darnold’s progress.

A few things to keep in mind. All rankings herein (other than the comparisons among the five 2018 first round rookie quarterbacks) are limited to rookie quarterbacks with at least 250 passing attempts in their rookie seasons. Prior to the 2018 season there have been 72 rookie quarterbacks with 250 or more passing attempts in the post merger era. Rate stats (like completion %) reflect actual current numbers for Darnold. Counting stats (like touchdowns or yards) reflect prorated numbers for Darnold assuming he continues to perform at the same level all season.

Let’s get to it. Below are a bunch of quarterback metrics, listing the all time rookie leaders for each and showing where Sam Darnold fits assuming he plays at the same level all season.

51. Sam Darnold 4.3

To provide additional context, we’ll see how Sam stacks up against the 42 qualifying rookie quarterbacks of the past 15 years. The game and its rules have changed so much that comparisons of quarterbacks from 50 years ago to quarterbacks of today are of limited value. Quarterbacks of the last 15 years make for a comparison much closer to apples to apples so to speak. Here is how Sam stacks up against rookie quarterbacks of the last 15 years:

The numbers here show Baker Mayfield to be by far the best of the rookie first round quarterbacks thus far, with Sam Darnold placed largely in the middle of the pack. One glaring issue with Darnold thus far is protecting the ball, as in interceptions Darnold lags in last place among his peers.

Finally let’s take a look at the numbers from the perspective of where Darnold ranks with respect to league averages compared to the post-merger rookie quarterbacks. We’re only going to be looking at rates here, not counting stats. Including this year’s qualifying rookies there have been 76 post-merger rookie quarterbacks with at least 250 passing attempts in their rookie year. The number listed next to the names corresponds to the percentage of league average for that player in his rookie year. So, for example, if a QB had a 60 passer rating in a year the league average was 80, his passer rating number here would be 60/80, or 75%. In this way we can compare quarterbacks across the eras on a level playing field, noting how they performed compared to the league in their time.

70. Sam Darnold 70

Here we see that Sam Darnold has been a mostly below average rookie quarterback when measured by percentage of league averages. He is below current NFL average in every major category, and compared to rookies across the years Sam is below average in passer rating and completion percentage, near the absolute bottom in interception percentage, about average in yards per attempt, and above average in touchdown percentage. All in all it has been a mixed bag for Sam’s rookie year compared to rookies since the merger.

With the year winding down Darnold has just two weeks remaining to tweak his numbers. His rising performances the last two weeks have begun to push him up the ranks a bit and spark some optimism in the Jets fan base. It would be nice to see him finish the year strong.
