Chicago could be Kovalchuk’s kind of town

The Blackhawks’ richest assets are on the blue line, where Duncan Keith, Brent Seabrook, and Brian Campbell retrieve pucks and trigger breakouts with their fleet feet and tape-to-tape passes.

But up front, where they already boast firepower in Patrick Kane, Jonathan Toews, Marian Hossa, and Patrick Sharp, it’s conceivable that they could become even more dangerous.

With Atlanta’s Ilya Kovalchuk due to become an unrestricted free agent after this season, and looking for a maximum contract (20 percent of the cap), the Thrashers may have to deal the 26-year-old sharpshooter prior to the March 3 deadline.

Chicago could enter the bidding with the notion of killing two birds with one stone: adding a top-five player to their roster for a Stanley Cup run while clearing cap space for next season.

According to a league source, the Blackhawks could use defenseman Cam Barker and ex-Bruin Kris Versteeg as the centerpieces of a Kovalchuk trade. Atlanta would most likely ask for a draft pick or two as well.

Two years ago, Thrashers general manager Don Waddell traded Hossa to Pittsburgh for Colby Armstrong, Erik Christensen, Angelo Esposito, and a first-round pick. The source said that if Waddell puts Kovalchuk (25-22 -47 in 37 games) in play, he will be looking for far more than he received for Hossa.

The Blackhawks would add a dynamic left wing and power-play specialist in Kovalchuk, who could play on the same line as Hossa. And if they don’t re-sign Kovalchuk, they would also clear salary in Barker and Versteeg (each player makes slightly more than $3 million) for 2010-11, when the extensions of Toews ($6.3 million), Kane ($6.3 million), and Keith ($5.5 million) kick in.
