NFL power rankings: Head coaches from 32-1

No. 25: Kyle Shanahan, San Francisco 49ers

Shanahan obviously goes to San Francisco with a familiar surname and a resume of success on his own as an offensive coordinator. The security of a six-year deal, in tandem with new general manager John Lynch, is also a good thing as the 49ers try to start a rebuild the right way.

But San Francisco also has one of the most talent-deficient rosters in the league. It may be a few years before they fully emerge from the mistakes of former general manager Trent Baalke and the shadow of former coach Jim Harbaugh, who led the franchise to its only notable success in the last decade.

Shanahan also carries some added expectations attached to what his father Mike did as a head coach, most notably two Super Bowl wins with the Denver Broncos. The team he has won’t meet those potential championship aspirations in 2017, probably 2018 and maybe beyond that. Finding a quarterback is the No. 1 priority, and it’s possible Kirk Cousins falls right into Shanahan’s lap in free agency next March. But a cultivation of a young quarterback won’t start until at least next year and without a fairly notable move in free agency to bridge the gap San Francisco’s win totals may suffer.

Shanahan has the luxury of time in San Francisco, as long as wonder boy owner Jed York doesn’t decide to change course and fire him quickly. But that’s about the only thing going for him right now in his first head coaching job, so Shanahan is sufficiently buried on this list.
