Interesting that in the Shark Pool, where every "is this trade fair" question is met with a barrage of "Let owners manage their own teams", there would be so many demanding rules that take decisions such as sitting or starting a position out of the hands of the owners.I guess manage the teams only refer to roster composition, not doing what you think gives your team the best chance to win a game on a given week.
Most starting postion rules in leagues are designed to punish inactive owners. I don't get the attitudes that demand that a team risk a W by forcing a start of an unfavorable matchup to comply. It wouldn't be an inactivity issue. Owners should be, assuming they are active, left to decide what is best for their team.If there is no rule, this is a fine tactical move to ensure a W. My $.02
In my $ league we have old school limited F/A moves and locked lineups the night before games so this wouldnt come up. Several teams carry one D or one K and take the "0" on the bye week with an incomplete lineup. Í think it's a risky move to sit the D in this scenario...as much as it's a risky move not to...Team management.
