The Blues shook up their defense Saturday, sending Roman Polak to the Toronto Maple Leafs for Carl Gunnarsson and a draft pick.
The Blues entered the offseason with seven defensemen under contract for the 2014-15 season, and despite some sentiment within the organization that a shakeup was needed, the club wasn't sure a trade was feasible.
On Day 2 of the NHL Draft, the Blues finalized one that filled several needs in their mind, particularly giving the team a left-handed shooting defenseman — to play with Kevin Shattenkirk — in exchange for a right-handed shot in Polak.
Gunnarsson, 27, has spent the past few seasons playing alongside Toronto captain Dion Phaneuf.
"We really believe the strength of our organization is our defense," Blues general manager Doug Armstrong said. "When you have players like (Jay) Bouwmeester, (Alex) Pietrangelo and Shattenkirk, you want to build around that and I think getting a left-handed player at Gunnarsson's age, with his track record of playing with a top player in Dion Phaneuf, and against top players in the league, this was something we needed to look at.
"As I say, to get a left-handed defenseman, you rob Peter to pay Paul we have to give up a right-handed defenseman and a quality person. We paid a strong price to get what we hope is a strong player. (But) it was a deal that we were very comfortable making. We could have used (Barret) Jackman or (Ian) Cole in that position, as we've done in the past. But you're always looking to tweak your roster and we were able to do that."
