Kessel's cap hit only worries me because i think they'll have to give up Pouliot to get him and the Pens will desperately need good, cheap defensemen to counteract how much salary would be tied up in Crosby/Malkin/Kessel/Letang. He doesn't make too much money, considering he's easily a top 5 winger in the league, but the Pens have more needs than just adding a top 6 winger and he'd complicate the process of fulfilling those needs. Not saying it wouldn't be worth it.
