Philadelphia Eagles defensive coordinator Vic Fangio has sparked intrigue across the NFL with his high praise for San Francisco 49ers backup quarterback Mac Jones, drawing direct comparisons to starter Brock Purdy just days before their NFC Wild Card playoff matchup.

In a media session on January 6, Fangio was asked about the potential differences in skill sets between Purdy and Jones, especially given concerns over Purdy’s health after he appeared to tweak something in the regular-season finale. Fangio’s response was candid and complimentary: “Not that much.” He highlighted the 49ers’ success during Jones’ stint as starter earlier in the season, noting that Jones started around eight games and led the team to a strong 5-3 record while Purdy was sidelined with an injury.

“They were very successful with Mac playing,” Fangio said. “Mac’s a really good quarterback and he’s where he should have been from the start.” This remark underscores Fangio’s belief that Jones thrives in Kyle Shanahan’s sophisticated offensive system, much like Purdy has since taking over as the 49ers’ starter.

The comparison is particularly noteworthy because both quarterbacks share traits that fit seamlessly into Shanahan’s scheme: quick processing, accuracy on the move, and the ability to execute play-action and bootlegs effectively. Purdy, the former “Mr. Irrelevant” draft pick, has established himself as one of the league’s most efficient passers, known for his poise in the pocket and extending plays with his legs while keeping his eyes downfield. Jones, after a challenging tenure with the New England Patriots and a brief stop elsewhere, found redemption in San Francisco this season. His performance in Purdy’s absence kept the 49ers’ playoff hopes alive, showcasing improved decision-making and command of the offense.

Fangio’s comments reflect a strategic mindset ahead of the playoff game. By downplaying any significant drop-off if Jones were to play, the veteran coordinator is preparing his defense for a consistent threat regardless of who lines up under center. The 49ers’ offense, powered by stars like Christian McCaffrey, George Kittle, and a talented receiving corps, remains potent with either quarterback. Shanahan’s play-calling emphasizes motion, misdirection, and timing routes that exploit defensive alignments—elements that both Purdy and Jones have executed well.

This praise also highlights Jones’ career resurgence. Once viewed as a potential franchise quarterback after a strong rookie year in New England, Jones faced criticism amid coaching changes and offensive struggles. His move to the 49ers in 2025 proved ideal, placing him in an environment tailored to his strengths: a strong supporting cast and a scheme that maximizes quarterback efficiency.

As the Eagles gear up to host the 49ers, Fangio’s defense—bolstered by an elite pass rush—will aim to disrupt this quarterback continuity. Yet his words serve as a reminder: San Francisco’s system elevates its signal-callers, making the Wild Card round a fascinating battle of schemes and execution.

Fans on both sides are buzzing, with some 49ers supporters hoping Purdy silences any doubts, while others appreciate the respect shown to their depth. One thing is clear—this playoff opener could feature high-level quarterback play, no matter the name on the jersey.
