If you're an NHL team looking for a goaltending upgrade, this summer's trade market could have just what you need with Jacob Markstrom, Linus Ullmark and Juuse Saros.

This summer's trade market could be a godsend for NHL clubs in the market for goaltending upgrades.

Jacob Markstrom of the Calgary Flames, Juuse Saros of the Nashville Predators and Linus Ullmark of the Boston Bruins frequently surfaced in the rumor mill before the March NHL trade deadline. 

Markstrom was reportedly close to being shipped to the New Jersey Devils last month. The deal fell through amid speculation that Flames ownership scuttled the trade. 

Ullmark used his 16-team no-trade clause to reject a trade to a Western Conference team (rumored to be the Los Angeles Kings) before the deadline. 

Predators GM Barry Trotz listened to offers for Saros, but none tempted him into moving the 28-year-old netminder. 

Last week, Sportsnet's Elliotte Friedman observed that Markstrom, Saros and Ullmark could become available again. It could set up what he believes would be an interesting trade market this summer for goaltenders. 

The Athletic's Jesse Granger suggested the Devils could be among their suitors. Granger cited Devils GM Tom Fitzgerald indicating he'd like to land one of the “big fish” this summer. 

As The Hockey News' Kristy Flannery noted, acquiring Kaapo Kahkonen and Jake Allen are considered stop-gap measures in net while Fitzgerald said the moves give them flexibility.

Granger expects the Devils won't be the only team interested in Markstrom, Saros or Ullmark. He speculated the Los Angeles Kings, Colorado Avalanche, Carolina Hurricanes and Toronto Maple Leafs could also get into the bidding. 

The Hockey News' Michael DeRosa suggested the Philadelphia Flyers and Columbus Blue Jackets among the suitors for Ullmark. 

Those clubs should be prepared to pay what could be high asking prices with a first-round pick and a top prospect or good young NHL player as part of the return. Their salaries will also be expensive to absorb. Markstrom carries an average annual value of $6 million for two more years, while Ullmark and Saros each carry $5 million for next season.

Saros is the only one lacking no-trade protection, per PuckPedia. Ullmark still has that no-trade clause though it drops to a 15-team list on July 1. Markstrom has a full no-movement clause.
