In 56 regular season games Lupul notched 20 goals and 26 assists. He missed significant time after a spine injury and concussion when he was hit by teammate Derian Hatcher. He also contributed 10 points in 17 playoff games this past season including the game seven overtime winner to end the Washington series.

According to NHL Numbers, Lupul is slated to make $2.9 million this season. He’s not quite going to make Jeff Carter money, but expect somewhere in the $3.25 million to $4.25 million range for Lupul. General Manager Paul Holmgren clearly has a set of core players he wants to build this team around for the future and this extension proves Lupul is among that nucleus.
