12 as One: Mike Macdonald, the Seattle Seahawks and the Making of a Super Bowl Champion

The definitive chronicle of the Seattle Seahawks' ascent to Super Bowl LX glory

Entering the 2025–26 NFL season, most observers expected either the Los Angeles Rams or the San Francisco 49ers to finish first in the NFC West, and many had the division-winner pegged for a spot in Super Bowl 60. After trading away their starting quarterback and top wide receiver, then signing free agent and onetime reclamation project Sam Darnold to take over under center, few believed the Seattle Seahawks had what it took to be a contender.

But the Seahawks believed.

Seattle rolled through the season and posted the best record in franchise history, vanquishing its West Coast foes on its way to the Super Bowl. There, in Levi’s Stadium, Seattle’s “Dark Side” defense manhandled the New England Patriots as the franchise won its second NFL championship.

12 as One, based on Michael-Shawn Dugar’s personal observations and in-the-room reporting, chronicles this unforgettable collection of players and personalities as they willed themselves to victory. Featuring insight into the leadership of the front office and head coach Mike Macdonald, as well as the performances of Darnold, Jaxon Smith-Njigba, Devon Witherspoon, Ernest Jones IV and others, 12 as One is an insightful exploration of the ties that bound them together and made the Seahawks more than the sum of their parts.
