You're probably right. But those must have been hold backs that the team released because every time I looked for tickets in the lower bowl (including clubs) for myself or friends on Ticketmaster, nothing was available.
The Devils often call regular season games a sellout where 1/3 of the club seats are empty (much like the Yankees, Giants and Jets - these teams don't consider premium club seating part of the general admission that counts towards what they determine is a reported sellout). However, that clearly wasn't the case during the playoffs as even the club sections were full.
True, but the Devils were being less than honest when the team website said that all tix were sold a few days earlier.
Really though, the complaint lies more with Ticketmaster. TM constantly hides the ball when it comes to saying what tickets are actually available and at what price, the obvious aim being to push fans into buying the more expensive seats. I just wish they would tell you upfront, before entering the Captcha and what seats you would prefer to buy, like they do on Stubhub.
