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

Other quarterbacks were 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 emergence since taking over for an injured Jimmy Garoppolo in Week 13 has caught the attention of the NFL world because the rookie quarterback wasn’t a top pick or second round. Nor was he a third or fourth rounder. Purdy was a seventh-round pick. Not only that, he was the last overall pick – No. 262 – in last year’s draft.

Yet here it is. Purdy has overcome the odds and proven he belongs. The rookie quarterback has yet to lose a game in which he started or played most snaps. He has played a significant role in each of the 49ers’ last eight games, all wins.

This week, Bleacher Report reminded fans that Purdy was the final pick in last year’s draft, noting, “Brock Purdy has proven the doubters wrong from the jump. I can’t write a better script for the rookie. .” (h/t Le filé)

A future Hall of Fame quarterback even responded to the post, messaging Purdy, 23, who is set to make his third playoff start.

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

Brady, of course, knows what it’s like to have second thoughts when entering the NFL. The quarterback was picked No. 199 in the 2000 NFL Draft.

On Sunday, Purdy can make his way into the NFL history books.
