This is idealistic silliness, in my opinion.
I can tell you in 1988 i was rooting for Cowboy losses like no tomorrow, and when Green Bay won a meaningless game on the last day of the season to ensure that we, and not they, would have the opportunity to draft Troy Aikman i was ecstatic.
Loser mentalities, what a crock, seriously. I can hear all those Packer fans now seated around their stoves talking about how 'dang nab proud' they are of their team not laying down and even though it cost them Aikman vs. Mandarich it ensured a winning culture going forward.
Most fans with any sense will always look at the big picture.
Every year is different, there are countless examples of teams sort of, kind of, maybe not giving it all to win everything late in a season. The following seasons are seldom dependent on the previous, especially if top talent is acquired because of it. There are too many factors, new players, new coaches etc.. etc..
I've seen a lot of posters in numerous threads taking a lot of heat for their subversive losing thinking, i would suggest their chastisers lay off the romance novels.
