OK, now I feel really excited like I am back to Oxford reading G.E. Moore articles against Kantian philosophy.
I do not think the definition of the term is so much of a problem - precisely because 'tanking' is a derogatory, humorous term that if defined precisely loses all of its charm.
But, here is the point. If this team is not going to make the playoffs, it makes more sense to finish as low as possible than to make wins. Sure, I would not go as far as saying that it makes sense to purposefully lose
every game (hey, even Philly had 19 wins last year; and we all understand that losing game after game would demolish the morale of our young talents). But, I think we all know the recipe: trading our only legit 3p shooter, ten-day contracts testing Blue Vader, resting our best players towards the end of the season, asking AB to take 11 3's against Philly (and yes, out-tank Hinkie in his own game). IMHO Ainge has already given signs he is willing to move to the same direction under the right circumstances.
It is an intelligent strategy, and it does not mean our players are out on the court to lose games. So, if the honour of the team is the issue here, I would not worry about that.
Anyway, back to Bertie fighting the German idealistic establishment
