The San Francisco 49ers are arguably the best team in the NFL, and it can also be argued who is most responsible for their success.

The Niners are 5-0 after demolishing the Dallas Cowboys, 42-10. Their point differential is plus-99, the highest in the league.

When he took over for Jimmy Garoppolo last year, quarterback Brock Purdy took the field alongside Christian McCaffrey, Deebo Samuel, George Kittle, Brandon Aiyuk, and a dominant offensive line. The Niners' elite defense also helps.

Purdy was the last player chosen in the 2022 NFL Draft and entered his first season as the third-string QB. But injuries to Trey Lance and Garoppolo put Purdy behind center, and Purdy has yet to lose a regular-season game.

Considering how stacked the 49ers are, some might argue there are plenty of quarterbacks who could take snaps for San Francisco and they'd be just as dominant.

Don't suggest that to Rob Gronkowski, who says San Fran struck "gold" with Purdy.

"It’s kind of easy to say you can plug in quarterbacks, and they would all be winners as well just because there’s so many weapons around them. But that’s how you win championships, man," Gronkowski told Fox News Digital in a recent interview.
