Guentzel did not leave the Penguins on the best of terms. He was particularly agitated by a perceived lack of forthright communication from Dubas, a source close to Guentzel said.
However, Guentzel would not deny Dubas an opportunity to pitch him on a potential return to Pittsburgh if Guentzel tests free agency in July.
Guentzel's fondness for the Penguins supersedes any ill feelings toward Dubas, said a team source and a source close to Guentzel.
Still, Guentzel reuniting with the Penguins was described by one source as "a long shot" because "he's loving it in Carolina, and (the Hurricanes) feel the same."
