Mammoth recall Daniil But, reassign Dmitri Simashev

The Mammoth are swapping a pair of their top prospects. The team announced they’ve recalled winger Daniil But from AHL Tucson while sending down defenseman Dmitriy Simashev in a corresponding move. Center Kevin Rooney was also placed on waivers and will be assigned to Tucson if he clears.

But and Simashev were both top-15 picks in the 2023 draft, the last premier prospects drafted under the Coyotes moniker before the franchise’s hockey operations were sold and reestablished in Utah. Simashev went sixth overall, while But went 12th. The two spent their entire careers in Lokomotiv Yaroslavl’s system in their native Russia, winning a Gagarin Cup championship together last year before signing their entry-level contracts and heading to the Mammoth for 2025-26.

While Simashev managed to wrestle a roster spot on the blue line, But was left on the outside as one of the Mammoth’s final roster cuts. He took the demotion in stride. After netting back-to-back 20-point seasons in the Kontinental Hockey League with Lokomotiv, he’s rattled off eight goals and 17 points in 19 games with Tucson to lead the club in scoring.

After a hot start to the season, Utah’s offense has cooled off. They’re now 19th in the league with 2.96 goals per game. Some of that can be attributed to a power play that’s languishing at a league-worst 13.2%, but their 10.3% finishing rate is also below average by a few ticks. Chance generation hasn’t been much of an issue – they’re 12th in shots per game and have the fifth-most scoring chances in the league at 5-on-5 – but the offensive output outside of their top five forwards leaves a little to be desired. Alexander Kerfoot’s persisting absence has been a contributing factor there, as well as underwhelming performances from middle-six centers Barrett Hayton and Jack McBain, who have five points each in 24 and 27 appearances, respectively.

But isn’t a guaranteed fix, but the 20-year-old’s smooth adjustment to North America shows he’s worth a shot. Most will see him listed at 6’5″ and 203 lbs and assume a high-ceiling power forward – he is not. Physical elements aren’t entirely absent from But’s game, but he’s a skill guy first and foremost. In their draft-year scouting report of But, Elite Prospects highlighted “his ability to chain difficult pass receptions into handling moves and handling moves into passes or shots” and praised his release as well. He’s another name in a star-studded Mammoth forward pool that’s now also gained Tij Iginla at sixth overall in 2024 and Caleb Desnoyers at fourth overall this year. Those two are viewed as slightly higher-ceiling talents, pushing But down to the No. 4-ranked prospect in Utah’s pool last offseason by Steven Ellis of Daily Faceoff and by NHL.com.
