It seems this question mirrors the same dilemma when the Colts would clinch early and sit their starters. Their reasoning is that their late season actions could improve their chances of winning it all. Same thinking used by the fantasy tankers. There is no guarantee that sitting your starters will insure you win the Super Bowl, but they feel it helps their chances. Them sitting their starters does have an impact on other teams in the NFL and possible playoff implications for OTHER teams. If they choose to do this strategy, they are concerned with their team and not the other teams. Just like in fantasy.
None of this makes it right, I just find it interesting that fantasy football does mirror NFL in this regard. I cant say the tankers are wrong (cuz I would be one), but I can say that each fantasy and NFL coach would approach this situation their own way. It seems the majority here would not stoop to that in order to win, but understand that some will take whatever advantage they can to win it all. For me I would do this if I felt I were at a disadvantage to other owners. Not necessary if I have a dominant team. Maybe I have learned too much from Belichick when it comes to playing on the edge of the rules.
Best way to avoid this every year is put something in the rules, but that would be a whole different thread.
