A couple of weeks, Pro-Football-Reference added a feature to its Player Game Finder tool where you can now filter games by whether a player started or came in as a substitution. While we have that data available for all offensive and defensive players back to just 1999, we actually have data for starting quarterbacks all the way back to 1950. So with that information, we have now added another section to the Player Game Finder where you can search for a range of QB career starts. Most statheads will likely use this for searches involving a QB's first career start or to find cumulative statistics through a QB's first x starts.
Here are some examples of searches you can now execute with this new addition:
Patrick Mahomes has made 17 career regular season starts at QB and continuously set "first x QB starts" records in 2018. Right now, he has a 6-TD and 587-yard lead over Kurt Warner's first 17 starts at QB. He is also just ahead of Warner and Dan Marino for best passer rating in a QB's first 17 starts.
Lamar Jackson appeared in several games in the first half of 2018 but didn't get his first start until Week 11, when he dazzled with 119 rushing yards in a win over Cincinnati. That day he set a post-merger record for most rushing yards in a player's first start at QB, passing Randall Cunningham and Tim Tebow.
Nick Mullens made his first career start on Thursday Night Football and torched the Raiders for 3 TDs and a 151.9 passer rating. That's the highest passer rating of any QB who's made their first NFL start in a non-Sunday game. Honorable mention goes to AFL-era Patriots primary punter Tom Yewcic, who got his first start at QB at the age of 30 on a Friday night and posted a passer rating of 152.6 in a win over the Bills.
