Logan Cooley depth is now one of the cleaner ways to judge the Utah Mammoth’s roster planning after a 2025-26 stretch that tested their center group. Cooley’s lower-body injury on December 5, 2025 against Vancouver removed their top young offensive center from the lineup for an extended period, and Utah had to survive without a player who had produced 23 points in his first 29 games, including a team-leading 14 goals at that time, as reported by ESPN’s injury report.
The Mammoth did not collapse without him. Their 14-9-1 mark during his absence, including a 9-2-1 run after January 1, 2026, suggests the staff found workable answers. That record should be read carefully, though. Winning through an absence is not the same as replacing the absent player’s skill set. Cooley’s speed, puck-carrying value and scoring profile still left a top-six creation gap that the rest of the forward group had to cover by committee.
Why Logan Cooley depth Matters
Injury Timeline And Immediate Stress
Cooley’s absence began on December 5, 2025 and lasted until his return on February 26, 2026 against the Colorado Avalanche. In that return game, he played 17:21 and recorded an assist in Utah’s loss, according to the Mammoth’s official game story. That workload was not a token return. It showed that once cleared, he immediately re-entered as a meaningful forward rather than a sheltered piece.
The roster question during the layoff was not whether Utah had NHL centers. It did. The sharper question was whether those centers could absorb top-six offensive duties without forcing the entire lineup out of shape. Barrett Hayton and Jack McBain could take minutes. Alex Kerfoot also helped in elevated and penalty-kill usage before later leaving in the offseason. But the available research points to a clear concern: Utah’s offensive creation from centers outside Cooley or Nick Schmaltz was not consistent enough to remove the need for another high-end option.
Logan Cooley depth And Center Usage
The practical question behind Logan Cooley depth is how much stress Utah can remove from one player. Cooley is projected as the No. 1 center for 2026-27, with Vincent Trocheck, Hayton, McBain and Kevin Stenlund forming the next layers down the middle. That is a more stable structure than the group Utah leaned on during the injury stretch.
Center depth has a different value than wing depth because it affects matchups, defensive-zone starts, special teams and late-game bench choices. If Cooley is available, the Mammoth can keep other centers in clearer lanes. If he is not, the team needs a second line of support that can create offense without reducing the checking value of the bottom six. The 2025-26 absence showed that Utah could manage games, but it also showed why management had reason to add another established center.
What The Mammoth Learned During The Absence
Results Without Their Young Center
Utah’s 14-9-1 stretch without Cooley was a positive signal for team structure. It suggested the Mammoth had enough defensive habits, goaltending support and forward buy-in to keep their results from swinging too far. The 9-2-1 record after January 1, 2026 was especially useful evidence that the coaching staff found combinations that could survive a difficult run.
Still, that record should not be used as proof that the Mammoth had solved the center issue. Short-term records can reflect schedule pockets, defensive discipline, special-teams runs or goaltending form. The more stable takeaway is that Utah’s baseline team play held up, while the top-six attack still lacked the same ceiling without Cooley’s individual threat. That difference matters for roster planning because the club was not only trying to stay competitive in December and January. It was building a forward group that could handle future absences without asking too many players to jump above their best roles.
Defense Helped Cover Forward Strain
The research indicates that Utah’s defensive profile remained solid while Cooley was out, including relatively strong shot suppression and goals-against results. That gave the forwards a cushion. If a team can limit chances against, it does not need every replacement center to produce like a first-line player. It can win lower-event games and keep the score state manageable.
That approach has limits. Forwards who slide into heavier minutes often face tougher matchups, more defensive-zone responsibility and less favorable shift timing. The Mammoth’s depth players handled enough of that burden to keep the standings damage under control. But the fact that the front office later added Trocheck shows that management did not treat the injury stretch as a finished answer.
How Trocheck And Lee Reframe The Forward Group
Veteran Center Insurance
On July 1, 2026, Utah acquired Vincent Trocheck from the New York Rangers. His 2025-26 production, 53 points in 67 games, gives the Mammoth a proven second center option behind Cooley. That is the most direct roster response to what happened during the injury absence. Trocheck does not need to replace Cooley’s long-term upside. He needs to reduce the cost of any missed time and give the coaching staff a credible matchup center when Cooley is healthy.
That is why Logan Cooley depth cannot be judged only by the first line. With Trocheck in the group, Hayton and McBain can sit in more defined roles. Stenlund also fits better when the club is not asking every center to create offense above his likely slot. The benefit is not just scoring. It is lineup order.
Utah also added Anders Lee on a three-year deal, giving the forward group a veteran winger with scoring depth and leadership value. That matters because center absences often force wingers into altered assignments. A more seasoned wing group can help stabilize lines when centers move up or down the lineup.
Kerfoot’s Exit Keeps Pressure On
Kerfoot’s offseason move to Nashville still matters in this calculation. During Cooley’s absence, Kerfoot had been one of the players trusted with top-six and penalty-kill duties. Removing that kind of utility can make a lineup thinner even after adding a more prominent center. Trocheck raises the ceiling of the center group, but Kerfoot’s departure removes one of the flexible pieces who helped bridge the hard months of 2025-26.
The Mammoth also lost Ian Cole and goaltender Vitek Vaneček during offseason movement. Those departures do not directly change Cooley’s center spot, but they are part of the same roster-depth equation. If the defense or goaltending depth becomes less stable, the forward group may have less margin to absorb another top-line absence.
- Cooley remains the clear offensive driver at center when healthy.
- Trocheck gives Utah a veteran buffer that did not exist in the same form during the injury stretch.
- Hayton, McBain and Stenlund gain value if they stay in roles that match their strengths.
- Kerfoot’s exit means Utah still has to replace some utility minutes.

What Logan Cooley Means For Utah’s Center Plan
A More Defined Lineup If Healthy
Cooley’s long-term standing in Utah is clear from the way the roster has been shaped around him. The research provided for this assessment lists an eight-year extension beginning in 2026-27 at a $10 million average annual value, making him the team’s highest-paid player. That kind of commitment aligns with his projected place as the No. 1 center and with the organization’s need to build a deeper spine behind him.
A realistic reading of Logan Cooley depth is that Utah is better prepared than it was on December 5, 2025, but not immune to pressure. The Mammoth proved they could win without him for a meaningful stretch. They also showed enough stress in top-six creation to justify the Trocheck move. If Cooley stays in the lineup, Trocheck, Hayton, McBain and Stenlund can form a cleaner center ladder. If absences return, Utah now has more insulation, though Kerfoot’s lost utility keeps the margin from being as wide as it may appear on paper.
The lesson from 2025-26 is not that Utah can simply absorb losing a foundational center. It is that a good defensive base, steadier role assignment and one added veteran center can turn a severe absence from a season-breaking event into a manageable roster test. For a Mammoth team trying to grow around Cooley, that distinction is the real measure of progress.
