I was thinking about plays or moments on the field that changed Cowboys History. There are many so here is mine.
1989 Aikman's throw against the Cardinals - It was the most astounding, accurate, and courageous throw I have every saw in pro football. Its was a 75 yd TD throw to James Dixon, in the closing moments of the game. Aikman stood in the pocket made the throw with a Cardinal DL in his face to blast the soul out of Aikman's body with the hit. He was knock out looking dead on the field after the hit. The pass was laser beam 75 yd. TD.
It affected Cowboys history in the following ways:
I. It showed you the glory and tragedy that would be Aikman's career. He would could win it all and give up all to win it all. Firmly ended all doubts by the Cowboys coaching staff that came from Miami who wanted Walsh at QB. Aikman was a franchise QB that could snatch a win from defeat or die trying (see 1994 NFC Championship lost).
2. Because the Cowboys defense would give up the win for the Cardinals the next drive causing Johnson to curse out Everson Walls for congratulating Cardinal Players after the game, it ended the mentality that Irvin warned Jimmy Johnson about the Dallas Cowboy complacency to losing. Everson Walls was cut at the end of the year. Jimmy established that only winning is expected and no reason to be happy with "keeping it close" and losing.
3. Allowed Steve Walsh to get starts so Johnson's master plan would yield the Saint's first and third round picks in the
1991 NFL Draft and a second round pick (that could become a first round pick based on performance) in the
1992 NFL Draft. for the Cowboys. Those drafts gave the Cowboys the 90's Dynasty.
