I really don't know if that's true, outside of Lafontaine not liking it. Whether Darcy was setting up the tank is speculation, but I'd imagine more likely than not. At least most people around here thought he was.
Outside of the President of Hockey Operations disagreeing with it? Yea... aside from that

Again, there is a big difference between what Regier was doing (deconstruction, acquire futures, begin the rebuilding process) and what Murray went in a did (actively build the worst team possible).
Lafontaine actually got rid of the best possible tank coach (Rolston), to try and bring in someone to motivate the team... he wasn't about tanking.
