Caleb Williams and what history tells us about a rookie quarterback's ability to start fast (2024)

There isn’t a position in professional sports that is more difficult or challenging than quarterback in the NFL. Not only is arm talent needed, but players must also be able to diagnose coverages, maneuver the pocket, have excellent vision, display impeccable timing, and have a certain level of moxie to their game. In other words, there’s a lot to handle, which can make starting out as a rookie a daunting task.

That’s what new Chicago Bears quarterback Caleb Williams is preparing to do. Williams was drafted with the No. 1 overall pick last April, and the team made it clear that he’s their Week 1 starter. It’s a first for the Bears, who have preferred to sit their prized rookie quarterbacks behind a veteran until they were deemed ready for action. Not with Williams. Right away, he’s been taking all of the first-team reps and is the clear-cut starter for a Bears team going into the season with playoff aspirations. To get there, though, they will need to start out on the right foot.

That can be challenging for rookie quarterbacks, however. Since the rookie wage scale was implemented back in 2011, 24 rookie quarterbacks have started for their team in Week 1. Some had success immediately (CJ Stroud), while others were thrown to the wolves (DeShone Kizer).

To determine if rookies really do struggle out of the gate when starting in Week 1, we took a look at various statistics from 23 of those quarterbacks over the course of their first four games as professionals. These include completion percentage, yards per game, touchdowns, interceptions, quarterback rating, and overall record. We also included their rookie season averages to compare and see if they improved or regressed as the year went on.

PLEASE NOTE: Because this list focuses on rookie quarterbacks who started Week 1, players who started a week later, like Deshaun Watson, Josh Allen, and Justin Herbert, were not included. Anthony Richardson was omitted since he only played in four games total his rookie year and left two of them early due to injury. All statistics used are courteous of Stathead.

With that, here are all 23 rookie quarterbacks:

Out of the 23 quarterbacks since 2011 who started in Week 1 of their rookie season:

3 players had a quarterback rating of over 100 over their first four weeks. 2 of them finished the season above that mark.
15 quarterbacks finished the season with a better quarterback rating than they had for the first four weeks.
8 had their quarterback rating vary less than three points from their first four weeks to their season average.
Russell Wilson had the largest quarterback rating improvement, going from 73.5 through four weeks to 100 as a season average. Carson Wentz had the worst, dropping from 103.5 to 79.3.
12 had a completion percentage below 60% to start the season.
10 had a higher completion percentage for the season than they had to start the year.
3 quarterbacks averaged over 300 passing yards over their first four weeks. None of them finished the season above that mark.
7 quarterbacks averaged fewer than 225 passing yards to start the season.
4 quarterbacks finished the season with a higher yards-per-game average than what they had to start the year.
9 quarterbacks threw more touchdowns than interceptions to start the year. 4 of them had one interception or less.
1 quarterback had a record over .500 after their first four games.

Results and takeaways

Just how difficult are the first four weeks of a season for a rookie quarterback? It depends on what data points you’re looking at. Close to half of the quarterbacks improved their completion percentage as the season progressed, while the other half saw it get worse. Interestingly enough, the vast majority of quarterbacks didn’t sustain their yardage totals as the season went on. The most relevant statistics, though, might be quarterback rating and touchdowns to interceptions.

The average quarterback rating among all players through four weeks was 79.5. Most rookies had quarterback ratings below 85 to start the year, which is well below the NFL average. Those ratings were impacted by the touchdown to interception ratio, which unsurprisingly wasn’t stellar. 15 players threw at least four interceptions over the course of their first four games, showing that defenses were capable of making them pay for their mistakes.

The final bit of relevant information is controversial when talking about quarterback statistics, but it deserves a mention. Dak Prescott was the only player to achieve a record better than .500 over his first four games as a professional. Even when players have had hot stretches, like CJ Stroud or Marcus Mariota, the team success wasn’t usually there. That sticks out when looking at what Williams could do with the Bears to start his career.

General manager Ryan Poles has done a phenomenal job on paper with building this roster to complement Williams and bring him along as best as possible. The team has more talent than many of these other rookie quarterbacks had to start their careers. Wins are not THE quarterback stat, but they should be factored in when talking about the complete puzzle. It just shouldn’t hold nearly as much weight as other stats.

If Williams can complete at least 60% of his passes, achieve a quarterback rating of over 80, and limit his interception totals to three or less after four games, he’ll already be in better shape to start the year than many of these quarterbacks before him. But that also goes to show starting off on the right foot isn’t always as easy as it sounds. With the Bears having a tough schedule to end the year, including having to play all of their divisional opponents, getting off to a fast start is paramount and that begins with Williams. We’ll see how the rookie does this September.
