While recent NFL history has plenty of success stories when it comes to rookie quarterbacks, Bears fans should prepare themselves for the most likely scenario: rookie quarterbacks struggle.
The 2021 season is the perfect case study.
All of the rookie quarterbacks were tremendous in the preseason. Trevor Lawrence went 11-for-12 with two touchdowns in his last action and Zach Wilson finished 9-for-11 with two scores. Those two are currently the lowest-rated passers with at least 20 attempts in the regular season. If you drop the number of minimum attempts to 15, the four lowest-rated passers in the league are Fields (38.2), Wilson (56.1), Lawrence (57.1) and Davis Mills (58.1).
But numbers don’t tell the whole story. Fields had a dropped touchdown pass that went right threw Allen Robinson’s arms. Even with that completion on Sunday, his passer rating would’ve only been 71. Maybe better chemistry with Darnell Mooney could’ve led to a couple of more completions, but the interception and the fumble still happened and were nearly catastrophic.
In August, Sheil Kapadia of The Athletic did a story looking at rookie quarterbacks, wherein he determined that 24 of the 31 were below average. “The median rookie season was Mike Glennon,” Kapadia wrote.
In the last five years, there have been 17 teams that have had rookie quarterbacks play extensively. Only two of those teams finished inside the top 15 in terms of scoring and three were in the top half of the league in yardage. From 2016 to 2019, the worst offenses in the league were all quarterbacked by rookies.
