ENGLEWOOD, Colo. – Peyton Manning impressively knows the history of 49ers quarterbacks, and he’s entertainingly sharing it through an ESPN and NFL Films project commemorating the NFL’s 100th season.

He’s sat with Joe Montana at Bill Walsh’s original desk inside the 49ers Museum. He’s tossed passes with Steve Young while lamenting the dearth of left-handed quarterbacks. And he’s marveled at John Brodie’s and Y.A. Tittle’s pioneering exploits at Kezar Stadium.
