From the Pittsburgh Post Gazette's Dave Molinari:
Matt Niskanen knows the numbers.
More important, he understands what they might mean for his future with the Penguins.
He's aware that the Penguins, who will open training camp next Wednesday, are roughly $1.1 million over the NHL's salary-cap ceiling of $64.3 million for the 2013-14 season.
He also realizes that their projected 23-man roster -- and it's far from certain they'll carry that many -- includes seven defensemen who would have to clear waivers and an eighth, Simon Despres, who is waiver-exempt, but who seems virtually certain to secure steady work in the NHL this winter.
It's no surprise, then, that Niskanen has been a fixture in trade speculation since the Penguins signed free-agent defenseman Rob Scuderi.
