Kevin Weekes hints at a major goaltending trade in the NHL.

Former National Hockey League goaltender Kevin Weekes appears to believe that we are on the verge of a truly massive trade.

On Friday, the NHL Network analyst published a not-so-cryptic message on his social media in which he advised his followers to keep an eye on Calgary Flames goaltender Jacob Markstrom.

Markstrom has been the subject of trade speculation for several weeks now, if not months, and a signal like this from a credible NHL insider like Weekes would appear to indicate that a trade may finally be around the corner.

There is no shortage of NHL teams that could use help between the pipes this season, including Canadian rivals the Toronto Maple Leafs and Alberta rivals the Edmonton Oilers, but moving Markstrom in a trade will still be easier said than done. The veteran goaltender carries an average annual value and cap hit of $6 million per season on his current deal, and has one more season remaining on that contract beyond this one.

Further complicating matters for the Flames here is the fact that Markstrom's deal also comes equipped with an ironclad full no movement clause through the entire length of the contract, likely limiting the number of options available to the Flames. Markstrom could of course agree to waive his no movement clause, which would eliminate that particular headache for the Flames.

In spite of some of the issues in moving Markstrom's contract, the veteran goaltender is having himself another solid season in spite of having a significant injury setback in December. Over his 25 appearances for the Flames this season Markstrom has recorded a 2.65 goals against average and a .910 save percentage.

The high level of demand for goaltenders around the NHL at this time should mean that the Flames are going to be looking at a significant return here, and that goes double if the Flames retain any salary in order to facilitate a trade to a cap team.
