We do learn that the tickets available free on Ticketmaster were actually purchased by the shopping site Saveology. The Times doesn't ask uber-marketer Brett Yormark for how much the team "sold" those tickets.
While the Times includes a dollop of skepticism, acknowledging the obvious, that "on some nights, the Izod Center’s attendance appears to fall far short of the average," Yormark gets five paragraphs in a brief story to tout the ticket exchange program with his brother Michael's equally-struggling-to-fill-seats Florida Panthers hockey team.
Unmentioned: how many people have actually taken advantage of the program.
A little more skepticism might have been in order. NLG pointed out that "the chances of anyone actually taking advantage of this silly promotion are slim." Bleacher Report commented: "Sounds great! Buy tickets to one team, get tickets to the other! Except the teams play different sports, and are kinda far apart."
Even a fan supportive of the Brooklyn move questioned Yormark's claim that attendance was down only 3%, writing on the NetsDaily comment board, "just 3%? strictly going by how many people i see at home games it seems like there are a lot more people staying home this season than last."
