Honestly? No. Not unless the sport of hockey becomes more popular.
The Nets had infinitely more advantages when they moved to Barclays in terms of marketing, full embracing of Brooklyn as their home, an arena that was designed specifically with basketball in mind, big media hype, a super rich owner, etc. Not to mention basketball has a ton more fans in NY than hockey, and the resident franchise, the Knicks, have been one of the worst franchises in sports for over a decade. The table was set for the Nets to become a big hit in NY...
...and they failed miserably. Turns out, building from an almost entirely new fanbase is pretty hard. And that's really what the Islanders (and Barclays) are banking on with this relationship. It's not about the Islanders' profit line in the short term, but their potential for growth.
The Islanders profits right now are aided heavily by the sweetheart deal that Barclays provided them. This is a trial run to see if the Isles can gain some traction in Brooklyn/NYC. Retaining the old fan base is nice, but if Barclays hasn't made it evident already, their give a crap level about hardcore Islanders fans is pretty low. They need the fanbase to grow and grow significantly.
Put differently: the Islanders are former homeowners who were foreclosed on. Barclays has a sweet house, and invited the Islanders to come over and live basically rent free for a while on the premise that they can get on their feet and maybe go halves on the mortgage at some point, and be successful. I mean hey, why not? Barclays owners need someone to live in and maintain the house for a bit. For the time being, it seems like this is an awesome deal for the Islanders because all of a sudden those paychecks look a lot fatter.
At some point, if they don't start growing and becoming a seriously profitable hockey franchise, the homeowner (Barclays) is going to start looking at the Isles like deadbeats if they don't start selling out more dates and growing the fanbase. So forget the $53 million per year profit. It's a band-aid. The question is and has always been: can the Islanders be a successful franchise in terms of fan base and business?
IMO, unless they can get a new arena built on LI around a big downtown hub like in Huntington or somewhere, ownership will realize that there is way more money to be made by moving the team to Seattle or somewhere else. Way too many cities are hot for an NHL franchise. This Isles situation is not going to just remain in a weird limbo where Barclays subsidizes them as an "also featuring" act.
I don't mean this in a spiteful way or anything. I'm a Rangers fan from LI that thinks the Islanders-Rangers rivalry is good for NY and good for hockey. I hope they find a way to make it back to the Island in a bigger way than ever, and we can have two very good teams (because the Isles on-ice product is the best it has been for many years, no question) in NY. But I just don't see Brooklyn working out at all. They had a hard enough time establishing a fanbase on the Island for decades because the Rangers had been around so long - now they're going to do it in the Rangers' back yard, for neo-Brooklynites who could probably give a crap less about sports in general? Doesn't look good IMO.
Well done. What he said.
