Kyle Shanahan has offered a candid assessment of why 44-year-old Philip Rivers remains more effective than many younger quarterbacks in today’s NFL, despite his recent return from retirement.
The San Francisco 49ers head coach – preparing to face Rivers and the Indianapolis Colts on Monday Night Football – didn’t hold back when discussing the veteran quarterback’s surprising effectiveness following his emergency signing after Daniel Jones’ season-ending injury.
“I mean, he is a little bit older. So, he might not be as fast, might not be able to throw it quite the same distance as he used to, but you don’t know that for sure because you don’t get to exactly see it on tape,” Shanahan told reporters this week. “But I see a guy who knows how to play the position as good as anyone.”
Rivers’ performance against Seattle’s defense particularly impressed the 49ers coach.
“Think he had 27 throws in that game [vs. Seattle], and every ball goes to the exact right spot,” he continued. “He attacked their coverages great. He played against a very good pass rush and was able to get rid of the ball.”
“He’s one of the best quarterbacks I’ve ever watched, and he definitely helped that team,” Shanahan concluded.

It’s mental processing – not physical tools – that sets Rivers apart.
Veteran quarterback Brian Hoyer echoed Shanahan’s assessment on Twitter, highlighting Rivers’ remarkable ability to diagnose defenses despite his lengthy absence from the game. “Kyle’s spot on about Phillip. It wasn’t too hard for Phillip to read defenses(Seattle top 5 defense) in 2025 after not playing for 5 years and with 3 days of preparation, but the case I hear for pure progression reads is that it’s ‘impossible’ to read coverage these days,” Hoyer wrote.

The matchup between the 10-4 49ers and 8-6 Colts carries significant playoff implications, especially for Indianapolis. The Colts enter as 3-point underdogs but desperately need a win to maintain their position in the race for the AFC’s final playoff spot.
Monday’s game will provide another opportunity to see if Rivers’ football IQ continues to overcome any physical limitations that come with being a 44-year-old quarterback in the NFL.
