I think people get the concept, they just don't agree with it. It's up to each fan to draw the line as to how far they would want a team to go to win (taking the long view here in your scenario).
It's against the rules, it's against the ethos of sports and for me personally I wouldn't want my team to lose even if I can understand the rationale behind it.
With the greatest respect, I understand your position and honestly you're correct. But that goes for every team, the worst finish is always going to be the SBowl runner up. If every team who's got no realistic shot started tanking it would soon make a farce of the league.
To that end, though I know realistically it is probably better we lose so we get a better pick and maybe even a change of FO, I'd still rather hang on to trying to enjoy things week to week until all hope has truly been extinguished. I mean if you want us to lose it must make it weirdly bittersweet when we actually do have positive plays?
