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 impo sible 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 pa ses, yards per pa s attempt and pa ser rating in that span.Here's a look at some of the improbable marks Aron Baynes Jersey he would reach by winning on Sunday.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 .

He would surpa s 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.Youngest QBs to Start Super BowlAge (Years-Days)Dan Marino (1984 Dolphins)23-127Ben Roethlisberger (2005 Steelers)23-340David Woodley (1982 Dolphins)24-097Jared Goff (2018 Rams)24-112You may have heard this before, but Purdy Ricky Rubio Jersey 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.Lowest-Drafted QBs to Start Super BowlOverall PickSeasonBrad Johnson227th2002David Woodley214th1982Joe Kapp209th1969Bart Starr200th1966-67Tom Brady199th10 timesFull disclosure, you could say this list is subjective, Jalen Lecque Jersey 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.Backup QBs to Start Super BowlTeamResultNick Foles2017 EaglesWonColin Kaepernick2012 49ersLostJake Delhomme2003 PanthersLostTom Brady2001 PatriotsWonTrent Dilfer2000 RavensWonKurt Warner1999 RamsWonJeff Hostetler1990 GiantsWonDoug Williams1987 WashingtonWonJim Plunkett1980 RaidersWonVince Ferragamo1979 RamsLostRoger Staubach1971 CowboysWonEarl Morrall1968 ColtsLostWhile 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 Chris Paul Jersey 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 surpa s, their stories, at least if you're looking at just their first Super Bowls.QBs to Start Super Bowl in First Season as StarterResultColin Kaepernick (2012 49ers)LostTom Brady (2001 Patriots)WonKurt Warner (1999 Rams)WonVince Ferragamo (1979 Rams)LostPurdy 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.Fewest Career Reg.

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.
