How do you measure Jordan Staal? By height, he's 6 feet 4. By his place in the Penguins lineup, he's a third-line center. Unless the team is experimenting with him as a second-line winger. Or unless one or both of the centers ahead of him are hurt as has been the case the past several months. By points, he is tied with winger James Neal for the team lead with nine going into the home game tonight against the New York Islanders. All those things offer tangible evidence of Staal's value, and there is more: Two of his six goals have come on the power play, and his .250 shooting percentage is the best on the team.
