Last year it was evident that such an operation can only work if people involved are micromanaged and forced to work within strong guidelines. Otherwise, it results in missed picks, complaints, people quitting, etc. That type of stuff is avoidable, but those of involved in orchestarting the mock draft have to take somewhat extreme measures to ensure that. Ideally, 32 responsible GMs will volunteer to participate, but that's not something I want to bank on.
