As far as what basis I would draw the line, logic and common sense are not absolute, but can be used for many of the examples you gave that are blatantly unethical. Anything giving someone an unfair advantage, not available to everyone, is cheating, and doesn't need a stated rule. This falls under common sense to me. A strategic decision, which is all we are talking about here? I have no problem with it. I certainly understand why people think it isn't within the spirit of competition, and wouldn't do it. But just because someone else feels that way, doesn't mean I should manage MY team differently. One other thing, tanking can be done subtly. An owner doesn't have to blatantly pull Carson Palmer for JP Losman. Or Frank Gore for Clinton Portis. it may be tanking, but if I am starting Ryan Grant over Steven Jackson, would you feel strongly enough to raise the issue, and force an owner to make roster changes? And what happens if Grant outperforms Jackson? And by starting Grant over Jackson, was the integrity of the league brought into question?
