Just a bit of history for the young ones, the trade was not Walker for draft picks. The Vikings GM at the time was Mike Lynn and he had built a perrenial playoff contender in MN. He was not a dumb man. But, what Jimmy did was so far outside the box of the NFL back in 1989 that nobody saw it coming........other than Jimmy. What Jimmy did which was so original and genius was tie each player MN traded to a draft pick. So, if Dallas cut the player, they would get the pick tied to that player. At the time, we were working on a 1-15 season and Jimmy was using the season as one long tryout to see who he wanted. It never occurred to Mike Lynn that a team so bad would cut all those quality players and MN would loose all those draft picks. Guys like Jessie Solomon, Isaac Holt, and Darren Nelson were really good NFL players who would have upgraded the 1989 team.
The trade was not popular in Dallas at the time. We loved hershel Walker. Many Cowboy fans and media were livid about trading our best player AND then turning around and cutting the players you got in return. It made no sense and looked like amateur hour ........ But, Jimmy never wanted the MN players. He wanted the draft picks, and he was alone on an island at the time.
Jerry deserves some credit. Though the trade was conceived and sold to Mike Lynn by Jimmy Johnson, Walker didn't want to go. Jerry stepped up and paid him 1M to accept the trade. (Back in 1989, that was like 5M today)........ without a salary cap, owners could do things like that in 1989.
