Conspiracy Theory time:
Sometimes I think half the players in leagues are just "dummy" owners. WIS sports/MSN employees who enter teams with free credits to keep interest in the site and just let the teams fly on their own. Why would you buy all those teams and not even try to understand the game? Why would you buy all those teams and just keep on losing.
There was one owner who had the stud year of Ty Cobb, and he had him sitting the bench for 140 games that season. It made no sense whatsoever. He wasn't trying to win. I mentioned it, he made a small comment about not knowing what I talking about a week later, but never changed his lineup.
If you're too busy to pay attention to the game, why flush your money down the toilet?
