San Francisco 49ers quarterback Brock Purdy could become the first rookie quarterback to start a Super Bowl. But first, he’ll need to get past the Philadelphia Eagles on Sunday. Purdy would become the fifth rookie quarterback to start a conference championship game since 1970. The other four lost their starts.

Other quarterbacks have been Shaun King of the Tampa Bay Buccaneers (1999), Ben Roethlisberger of the Pittsburgh Steelers (2004), Joe Flacco of the Baltimore Ravens (2008), and Mark Sanchez of the New York Jets (2009). Three of those quarterbacks were first-round picks. King was a second-round pick.

Purdy’s appearance since taking over an injured Jimmy Garoppolo in Week 13 caught the attention of the NFL world because the rookie quarterback was not a first or second round pick. It wasn’t fourth or third either. Purdy was a seventh-round pick. Not only that, it was the last overall pick—no. 262 – in last year’s draft.

However, here it is. Purdy beat the odds and proved he belonged. The rookie quarterback has not yet lost the game in which he started or played the most snaps. He’s played an important role in each of the 49ers’ last eight games – all wins.

This week, Bleacher Report reminded fans that Purdy was the last overall pick in last year’s draft, stating, “Brock Purdy proved the doubters wrong from the jump. A better rookie script couldn’t be written.” (h/t The Spun)

One future Hall of Fame inductee even responded to the post, sending a message to 23-year-old Purdy, who is slated to make his third playoff start.

“Prove them wrong or prove them right!” Tom Brady replied in the comments.

Brady, of course, knows what it’s like to have skeptics going into the NFL. Selected 199th quarterback of the 2000 NFL Draft.

On Sunday, Purdy could make its way into the NFL history books.
