Brock Purdy, Mr. Irrelevant, is one step away from reaching heights no other rookie QB has ever reached in NFL history, let alone the last pick of the NFL Draft. If the 49ers reach the Super Bowl, or even win, this tale goes from improbable to one of the most impossible feats in sports history. 

It's within his grasp, and the way he's been playing, it's becoming quite realistic. He's a perfect 7-0 since taking over as the 49ers starting QB, and he even leads the NFL in touchdown passes, yards per pass attempt and passer rating in that span.

Here's a look at some of the improbable marks he would reach by winning on Sunday.

First rookie QB to start Super Bowl

Purdy would be the first rookie QB to ever start a Super Bowl. He's the fifth rookie QB to start a conference championship game, and the previous four had a rough go of it, as we documented earlier this week.

Youngest QB to start Super Bowl

Purdy will be 23 years and 47 days old on the day of Super Bowl LVII. He would surpass Dan Marino (an older 23) as the youngest quarterback to start a Super Bowl ever. It just so happens that Purdy wears No. 13 in honor of Marino, as his dad grew up a Dolphins fan. If you're looking to stump your friends with a trivia question, the only other QB to start a Super Bowl wearing No. 13 (besides Marino) is Kurt Warner.

Lowest-drafted QB to start Super Bowl

You may have heard this before, but Purdy was the last pick of the 2022 NFL Draft. He'd be the lowest-drafted QB to ever start a Super Bowl (262nd overall). The mark currently belongs to Brad Johnson, who was the 227th pick in the ninth round of the 1992 NFL Draft, and won Super Bowl XXXVII with the Buccaneers. Of course, I can't forget to mention two undrafted QBs have started a Super Bowl, Kurt Warner and Jake Delhomme.

13th backup QB (and first 3rd-string QB) to start Super Bowl

Full disclosure, you could say this list is subjective, but after combing through every Super Bowl starting QB I'm confident that Purdy would be the 13th backup QB to start in a Super Bowl, and the first 3rd-string QB. There's good symmetry here too, as the last backup QB to do this was Nick Foles in the 2017 season. Purdy, of course, has to get through Foles' old team, the Eagles, to reach Super Bowl LVII.

Fifth QB to start Super Bowl in first season as a starter

While Purdy would be the first rookie QB to start a Super Bowl, it's worth mentioning some others who burst onto the scene and made the big game. Purdy would be the fifth QB to start a Super Bowl in his first season as a starter, along with Colin Kaepernick, Tom Brady, Kurt Warner and Vince Ferragamo. Brady and Warner, who have authored two of the best underdog stories in league history, were the only two QBs to win a Super Bowl in their first season as a starter. Safe to say a championship by Purdy would rival, and probably surpass, their stories, at least if you're looking at just their first Super Bowls.

Second-fewest career starts entering Super Bowl start

Purdy would be without a doubt one of the least-experienced signal callers to start in the Super Bowl. His five career regular-season starts would be tied for the second-fewest for any starting QB entering the Super Bowl. Jeff Hostetler had just four starts in his career before leading the Giants to a win in Super Bowl XXV to cap the 1990 season.

Third Mr. Irrelevant to play in Super Bowl

And fittingly saving the best for last, Purdy can become the third Mr. Irrelevant to play in a Super Bowl. Linebacker Marty Moore, the final pick of the 1994 NFL Draft, played in Super Bowl XXXI with the Patriots (lost to Packers). Kicker Ryan Succop, the final pick of the 2009 NFL Draft, won Super Bowl LV with the Buccaneers vs the Chiefs.
