If you were wondering why 49ers rookie quarterback has maintained a poised and confident nature , it’s not on accident.

The 23-year-old is on the verge of rewriting NFL history and is one win away from taking the 49ers’ storybook 2022 season to Glendale, Ariz., for Super Bowl LVII.

But as he reflects on the season in what’s been anything but a typical rookie experience, Purdy the NFL has taught him.

“I would just say not getting too high and not getting too low,” Purdy told reporters Friday. “There’s definitely been times in the game where you think things are going well and you think, ‘Man, this isn’t as bad,’ but then you get humbled real quick.

“So I think there are some good lessons that I’ve learned so far where you feel like things are going well and you just got to stay even-keeled. You got to go play another drive, another possession or another quarter. It’s the NFL. Everyone is good. It doesn’t matter how good you feel going into a game, you can get humbled real quick. Kyle [Shanahan] told me about that recently and I feel like it’s definitely stood out to me.”

That explains why the young QB always appears to be so cool, calm and collected on the field.

When went down with a season-ending foot injury in the 49ers’ Week 13 win over the on Dec. 4, Purdy’s name was called. He didn’t panic, he didn’t disappoint and he definitely didn’t look like a rookie.

That has been the continued storyline for Purdy, as his record as a starter (9-0) remains perfect.

He’s now one win away from leading the 49ers to Super Bowl LVII, but first, he . Purdy will play in his first NFL road playoff game when San Francisco takes on the in the NFC Championship Game on Sunday at Lincoln Financial Field.

But as he said, not too high, not too low. That surely will be the theme for Purdy and the 49ers come Sunday.
