In short, Oakland and Miami bring to the playoffs the best in speed ( Paul Warfield, Mercury Morris, Cliff Branch), the best in quarterbacking ( Bob Griese and Ken Stabler) and the best in genius ( Don Shula, Al Davis). These are consistently winning teams, well-rounded and pretty exciting, if you don't mind watching an occasional Larry Csonka or Marv Hubbard.
For connoisseurs of the playoff teams, here is some bric-a-brac:
Washington played the toughest regular-season schedule in the National Conference, Buffalo in the American.
Minnesota played the easiest schedule in the National, eight of its 10 victories coming against teams at or under .500, and Pittsburgh played the easiest in the American.
Only Oakland avoided losing games to teams at or under .500.
St. Louis and L.A. both lost games to New Orleans.
Minnesota and L.A. both lost games to Green Bay.
Pittsburgh and Buffalo both lost games to Houston.
Miami and Buffalo both lost games to the Jets.
Two black quarterbacks made the playoffs, Harris and Joe Gilliam.
