The trade that never ends, MacKenzie Weegar just proved it again

Frank Seravalli flagged it as one of those «wait, this is still going» moments. A 2022 blockbuster and a 2023 deadline swing both reached forward into Wednesday's news.

This is what trade trees really are. A big deal spits out picks, those picks get flipped, and years later you're still cashing the receipt.

Calgary dealt Weegar to the Utah Mammoth. That sentence alone carries history, because Weegar arrived in Alberta through the Matthew Tkachuk blockbuster.

Now the Flames are flipping that same chip for volume. Utah sent back Olli Määttä, prospect Jonathan Castagna, and three second-round picks in the 2026 draft.

Those three second-rounders are the real twist. They can linger for years, but they're still easy enough to move

One of them is especially spicy for Ottawa fans. The Ottawa Senators' 2026 second-rounder traces back to the Jakob Chychrun trade from March 1, 2023.

So yes, one old move can literally fall into another old move. That's why Seravalli called it a couple of trade trees adding a fresh branch.

Weegar isn't a throw-in either. He's got 3-18-21 in 60 games this season, and he plays the kind of minutes contenders pay for.

His cap hit is $6.25 million, and there are still five seasons left on that deal. That's a massive commitment for Utah, and a massive escape hatch for Calgary.

Flames fans are going to feel two things at once, relief at the futures, and sadness because this is a real «end of an era» trade.

Castagna is the quiet detail that matters. He's 20, drafted in 2023 in the third round by Arizona, and he's having a strong year at Cornell.

For Calgary, this is asset stacking with purpose. Picks plus a young center prospect fits a team that wants a longer runway.

For Utah, it's the opposite vibe. This is a «we want grown-up hockey now» bet on the blue line.

And that's the weird beauty of trade trees. They don't stop, they just change hands, then show up again when you least expect it.
