Late in 2024, the San Francisco 49ers defense saw firsthand what it'd be like without All-Pro defensive end Nick Bosa in the lineup, and the results weren't pretty.
In fact, the results without Bosa haven't been pretty ever since the Niners grabbed him in Round 1 of the 2019 NFL Draft.
Bosa, of course, suffered a torn ACL in San Francisco's Week 3 victory over the Arizona Cardinals, ending his season and putting coordinator Robert Saleh's defense in a massive bind for the rest of the season.
And a mere one game against the visiting Jacksonville Jaguars in Week 4 showcased just why Bosa is so important.
