Even strength scoring
This stat is too often overlooked. Although the Zetterberg-Datsyuk-Holmstrom line is potent when together, they don't dominate the team in even-strength goals. A pretty balanced second line can be formed without splitting Zetterberg and Datsyuk.
Also, Mathieu Schneider had a reputation as a power-play guy, but he was lethal at even strength. In Schneider's three full seasons in Detroit, he had 9, 10 and 10 even-strength goals. Brian Rafalski isn't nearly as productive at even strength as Schneider, but is better on the power play.
