Dat and Coakley were both under 6 foot tall. Parcells came in laughing at the fact we had two starting Linebackers smaller then running backs. He ended up respecting them both more then any other players on this team.
Parcell's first season as HC was a transition year for the Cowboys defense. Parcells did not have the time or the right manpower to use the 3-4 defense that was his preference. However, he did install some 3-4 concepts into the 4-3 that he used that season.
The irony is that this lame duck 4-3 defense, with Coakley and Nguyen, produced the highest ranking stats in the history of the Cowboys. They were ranked #1 in yardage and #2 in scoring. No other defense had ever produced a higher combination.
This team had coaches like Tom Landry and Jimmy Johnson, both producing legendary defenses. And, yet, neither ever produced a defense that was ranked as highly as the one in Parcells first season. Again, this was a temporary defense. Two seasons later Parcells switched to a 3-4.
