Biggest winners, losers from Nick Bosa's massive extension from 49ers

Winner: 49ers coordinator Steve Wilks

New Niners defensive coordinator Steve Wilks inherited the best defensive in the NFL when he took over the job from now-Houston Texans head coach DeMeco Ryans during the offseason.

However, maintaining that spot would have been exceptionally more difficult had Bosa not been available for the first week-plus of the regular season.

Last June, Wilks told reporters (h/t Niners Nation) about how focused and talented Bosa was:

"One of the things [Bosa and I] talked about is just his commitment to this game and him still trying to get better, defensive player of the year and can I take the next step? Can I do it again? He has that focus and determination, so I just love coaching guys like that, it’s not about my status. It’s definitely not about the money. He’s committed to trying to be one of the best."

Sure, San Francisco's defense is still plenty talented without Bosa, boasting additional All-Pros like linebacker Fred Warner and safety Talanoa Hufanga.

But Bosa brings Wilks' unit to an entirely different level, and the defensive coordinator is a clear winner because of it.
