No Dallas lost to the Packers in 66 & 67. Cleveland in 68 & 69 and the Colts in 70. They beat the Dolphins in
71 to win their first championship.
I had to look it up,but remembered the Browns had beaten them twice in the semi- finals. Cleveland is The
forgotten team during that era. Jim Brown retired in 65,but they were still a very good team a few years after.
