Didnt Red buy the Vikes for around 250 mill? and then sold them for over 600 mill? I dont remember but i sure do know that he made a killing of the sale of the team.
I think that there are many things that have played into the Vikings' recent history.
1. Red McCombs was a terrible owner. He was not willing to do anyhting to help the team. He was just using the position to make money. Which I don't know if he did if you just look at how much he bought the team for vs. the money he got for it, but he definitely made money off the team during the seasons that he was in charge. Tickets, merchandise, concessions, media, etc. He held this franchise back, not allowing for any progress. He didn't want to go get players, and he definitely didn't keep anyone happy.
2. Robert Smith's retirement. This is not anything that I hold against the man, but it left the team in a very tough situation. The team had to draft runningbacks to try and fill the void that was created when this great football player left. All this lead to the inability for the Vikings to draft talent at other positions.
3. Denny left the team in the hands of an assistant. Sure Denny didn't make the decision to hire Tice as the head coach, but he sure did leave his players hanging high and dry. I don't think that any of the players that played under Denny ever respected Tice. He just never was able to move past the "I'm your buddy, you know the assistant coach" phase.
4. The death of the late Korey Stringer. I just can't put into words the impact that this has had on the Vikings.
