In 1981 the Dallas Cowboys ran the ball a franchise record 630 times and was the #1 rushing team in the league. Tony Dorsett made 1st team All Pro with 1646 yards rushing. His FB, Ron Springs, ran for 625 yards. They absolutely hogged the time of possession and this placed an incredible burden on opponent offenses. Ironically, most analysts did not think the Cowboy could succeed that season because their secondary had been completely depleted due to retirement.
The secondary in 1981 consisted of a 33 year old Charlie Waters, former 11th round pick Dennis Thurman and two undrafted free agent rookies Everson Walls and Michael Downs. All they did was set a then NFL record in interceptions. the two CB's, Thurman and Walls, combined for 20 INTs. The safeties, Downs and Waters chipped in an additional 10.
That team seemed destined to go all the way but in the NFC championship game, Joe Montana threw this pass, there was a "catch" and the rest is history.
The point is, the strong running game created a domino effect that resulted in an historic season for a very young, inexperienced secondary.
This is why I predict that the Cowboy secondary will not be a detriment towards getting to the Super Bowl this season. In fact, their potential is extremely exciting.
