The Devils are a weird franchise. 3 Stanley Cups in a matter of 7-8 years and yet they can't keep their fan base interested. Maybe it's over saturation in the New York/New Jersey market, I don't know. But they've got one of the greatest goalies of all time playing for them, they had one of the biggest American names in hockey playing for them up until last year (Parise), they had a few season of Kovalchuk, and yet The Rock is rarely filled up. It's hard to remember they were in the Stanley Cup finals just last year.
That said, I don't think the NHL's takeover of the Devils will last as long as the Coyotes.
