Carolina Hurricanes owner Peter Karmanos Jr. said Friday that negotiations continue with sports attorney Chuck Greenberg over the proposed sale of the NHL team. But Karmanos, in an interview, said he has questions as to whether Greenberg will be able to form an investment group capable of raising the amount needed to buy the team – perhaps $500 million or more. “The sale of the team is just sitting there, waiting for Chuck to say, ‘Geez, I can’t raise the money,’ ” Karmanos said. “We have a commitment to Chuck, and we’re going to see it through. And quite frankly I wish he would pick up the phone and say, ‘Geez, you know what, I can’t get it done.’ Because it looks like he can’t get it done.” Asked if he believed Greenberg would be able to pull together a group of investors capable of completing the sale, Karmanos said, “Your guess is as good as mine.” In the past few days, those close to the negotiations have said some complications have arisen and the process has snagged.
