The Thrashers are last in the NHL in attendance, averaging 13,943 tickets distributed (which importantly includes both paid and comp'ed). The Gladiators official attendance was just 3014 on Tuesday. Both of those are indeed bad.
But, the AHL Lowell Devils sold just 904 tickets yesterday for a game. 904. If they weren't owned by the New Jersey Devils, who can afford to operate them at a loss, they'd be tops on the death pool.
An illustration of how bad it looks out there -- Glads stands at puckdrop, and this was the full side.
And other angles at the same point in time.
