History, now, are the Olympic Games.

Next up? The Obvious Games.

Because for rebuilding outfits, such as the Calgary Flames, the days leading up to the National Hockey League trade deadline hold little mystery.

Their motivation is selling. There’s no other way.

Brian Burke, back from Sochi, has until March 5 — a little more than a week — to transform outgoing assets into prospects and picks. In other words, a future.

The Flames boss has prioritized the team’s needs — getting bigger and tougher; upgrading his blue line. And he does have a few chips.

The most popular way of divining those on the trade block is contract status. Pending unrestricted free agents — chaps in their final year of their deals — on lowly squads are always candidates for greener pastures.

Fitting that bill for the 27th-place Flames are forwards Michael Cammalleri, Lee Stempniak, Kevin Westgarth, Blair Jones, Ben Street; defencemen Chris Butler, Derek Smith, Chris Breen; goaltenders Reto Berra, Joey MacDonald.

Cammalleri, 31, remains the most intriguing piece. A fact lost on no one.

On the night of his season’s debut — delayed till Oct. 21 because of a wrist injury — 25 (!) scouts showed up at the Staples Center. Cammalleri recorded two points that night.

In 41 dates, the wee winger has compiled 21 points, including 13 goals.

On the mind of any tire-kicking general manager, of course, is Cammalleri’s 2009-10 post-season. On behalf of the Montreal Canadiens, he drained 13 goals in 19 games.
