Flames Trade Weegar to Utah for 3 Second-Rounders, Maatta, Castagna
The Calgary Flames traded 31-year-old defenseman MacKenzie Weegar to the Utah Mammoth late Wednesday, receiving three 2026 second-round draft picks, veteran defender Olli Maatta, and Cornell sophomore Jonathan Castagna. The swap comes two weeks after Calgary dealt Rasmus Andersson for future assets, cementing the club’s pivot toward a full rebuild.
Flames Swap Weegar for Three 2026 Second-Round Picks
Weegar logged 24:17 per game this season and ranked second among Calgary defensemen with 42 points. He waived a partial no-trade clause to join Utah, which has now imported three top-four blueliners since last summer. The return gives Calgary six selections in the first three rounds of the June draft in Las Vegas and one of the league’s deepest prospect pools. General manager Craig Conroy said the 27-32-6 record at the Olympic break left no choice. “When you’re sitting where we are, you have to look three or four years out,” Conroy told Flames TV. “Adding multiple swings at a deep draft, plus a character veteran in Maatta and a pacey forward in Castagna, lines up with every checkpoint on our timeline.”
Utah Mammoth Land Top-Pair Defenseman for Playoff Push
Utah, clinging to the first Western wild-card berth, views Weegar as the final piece of a retooled top four that already includes Mikhail Sergachev and John Marino. The Mammoth have allowed the seventh-fewest shots since Christmas; adding a right-shot workhorse who kills penalties and quarterbacks the second power-play unit lifts them into the same conversation as Dallas and Winnipeg on paper. Utah GM Bill Armstrong paid a steep price—his club now owns only one second-round pick through 2028—but argued the cost beats shopping for a rental before Friday’s deadline. Weegar is signed through 2031 at a $6.25 million cap hit, giving the first-year franchise cost certainty it has sought while building an identity in Salt Lake City.
Calgary Adds Veteran Maatta and College Scorer
Olli Maatta, a two-time Stanley Cup winner with Pittsburgh, will report to the AHL’s Calgary Wranglers while the parent club auditions younger defenders. The 31-year-old Finn averaged a career-low 12:10 per night in Tampa’s load-management system, yet the Flames value his 97 games of postseason experience. Jonathan Castagna, 20, posted 14 goals and 32 points in 29 games for Cornell and earned ECAC Player of the Week honors in February. Scouts tag the 5-foot-11 winger as a relentless forechecker who wins more wall battles than his frame suggests. Calgary will burn the first year of his entry-level deal once Cornell’s season ends next week.
Fan Reaction: Jerseys Stashed, Hope Raised
Within minutes, #ThankYouWeegs trended across Alberta as fans saluted the defenseman who once urged city council to replace the aging Saddledome—comments many credit with accelerating the $1.2-billion Calgary Event Centre now under construction. “He literally spoke a new rink into existence; retire his voice,” tweeted @TyVanDusen7. Others swallowed the pain. “I bought my Weegar jersey last year, but I’ll stash it if it means we finally stop being mediocre,” wrote Reddit user FlamesFan884. Conroy acknowledged the emotional toll yet pleaded for patience: “We’re not tearing down for the sake of tearing down. We’re stockpiling bullets in what scouts tell us is a banner draft.”
Calgary Controls 10 Picks in 2026 Draft Weekends
Including the Andersson return—Vegas’s 2027 first-rounder and a 2028 second—Calgary owns ten selections across the next two draft classes. The club projects two first-rounders this June: its own lottery ticket (currently sixth) and Florida’s first obtained in last summer’s Reinhart deal. With the deadline looming Friday, veterans Nazem Kadri, Blake Coleman, and newly acquired Zach Whitecloud remain on the block, so the total could still climb. “Going to keep the scouts busy this year,” analytics account CapWages posted, a line Conroy echoed while insisting “we won’t make a move unless it checks every box—today was the template.”
What to Watch Next
- June 20-21: Calgary could make five picks on day one and two in Las Vegas.
- Castagna’s final games at Cornell; the Flames plan to sign him within days of the Big Red’s playoff exit.
- Utah’s postseason run—the deeper Weegar goes, the later Vegas’s 2027 first-rounder lands, potentially sweetening Calgary’s haul.
- Saddledome nights will feature more prospects than stars; roster spots are openly earmarked for youth auditions.
