You have to remember that hockey is relatively new to native North Carolinian's and transplants come with their own favorite team.
Youth hockey is growing in the Triangle, but was largely ignored with Karmanos at the helm. He was pumping his money into Detroit youth hockey. Now that Dundon is in charge, he sees the value in building the future fanbase through the kids.
Winning is also important to convert some of the transplants.
Well this isn't true at all. Hockey has existed in Raleigh continuously for the past 28 years between the Raleigh IceCaps of the ECHL and the Carolina Hurricanes. The IceCaps played in Dorton Arena, which is located within the State Fairgrounds campus that PNC Arena is adjacent to, sharing many of the same parking lots. And its older if you go out to Greensboro (where the Generals existed from 1959-1977 before being brought back in 1999) or Charlotte, where the Checkers have existed since 1955. Minor league hockey has deep roots in this region.
As for the Canes, I can speak for myself and say I bought season tickets for next year after being away the past few. The team over the last few years just wasn't worth spending money to watch. Karmanos didn't care about the talent, he just cared about keeping expenses low, so I protested with my wallet, knowing the second they gave me a reason to invest, I would do so. And now, I'm a full season ticket holder for next year, and I have run into numerous people who have shared a similar thought. Yes, there is a lot of bandwagoners with this run, which you expect anywhere, but there are also A LOT of old time fans who are coming back out. Which shows that hockey here is strong when you have the fans engaged. Given them a reason to care and they'll return the favor. And for the first time in a long ass time, I actually believe that ownership here actually cares to put a winning team on the ice.
