SANTA CLARA, Calif. — The San Francisco 49ers and the Dallas Cowboys, two of the N.F.L.’s most popular franchises, had one of the league’s premier rivalries throughout the 1980 and ’90s.
The Cowboys won three Super Bowls in four years and the 49ers won four titles in the 1980s. Often, one team’s biggest obstacle to winning a championship was the other.
In meetings this week, 49ers Coach Kyle Shanahan, whose father, Mike, worked on the 49ers’ coaching staff from 1992 to 1994, said he showed the team film from some of the most memorable games in the rivalry.
