When the St. Louis Blues acquired Alexander Steen way back in 2008, most fans knew little about him. All we really knew was the Blues might have been giving up on Lee Stempniak too soon and picking up two unknowns.
The reality was the Blues got a steady defender in Carlo Coliaccovo, Stempniak had a few flashes here or there but did not amount to much. Steen turned out to be the gem of the deal, providing a good scoring touch earlier in his Blues tenure and a hard-nosed defensive style as he got older and the Blues would advance farther in the playoffs.
