Utah's Preseason OT Defeat Highlights O'Brien's Surge and Roster Crunch
The Utah Mammoth fell 5-4 in overtime to the Vegas Golden Knights in their third preseason contest, with several fringe players making strong cases for roster spots. Veteran forward Liam O'Brien scored in a second straight game, showing improved skating while retaining his physical edge. The team faces tough decisions by Monday, as rookie Daniil But's standout camp could push a depth player off the 23-man roster.
O'Brien's two-goal preseason surge comes as the Mammoth face a Monday deadline to trim their roster to 23 players. His improved skating, paired with his established physical game—including a fight Tuesday against Los Angeles—makes him a difficult cut, especially with Brandon Tanev struggling to make an impact. Kevin Stenlund's three-assist night further complicates the front-office decisions.
The defensive corps also made its case, with three of Utah's four goals coming from blueliners, two from rookies. Dmitri Simashev logged 21:44, showing physical pushback when he confronted Ivan Barbashev after a hit on Tanev. Head coach André Tourigny praised both O'Brien and Stenlund, while rookie Daniil But's standout camp threatens to displace a veteran depth forward.
This roster crunch could reshape the Mammoth's early-season identity, as fans may see a younger, faster lineup if rookies like But and Simashev earn spots over established grinders. The decision affects not just player careers but team chemistry and physicality, which could influence Utah's competitiveness in tight divisional games. For players sent down, the demotion may alter their development trajectory, while the organization balances short-term wins against long-term growth.
