Utah Mammoth vs St. Louis Blues: a 37.1% power play against an 85.7% penalty kill, on the second night of a back-to-back 
Utah’s power play has scored 23 times on 62 chances this season, a 37.1% conversion rate. The same team kills only 69.6% of its own penalties and has allowed 63 goals in 18 games, which leaves the Mammoth with a goal difference of exactly zero despite the sixth-best attack in the NHL.
The Mammoth host St. Louis at the Delta Center in Salt Lake City on Thursday 12 November, with puck drop at 9:00pm ET. The scheduling matters. Utah play in Las Vegas the night before, at 10:00pm ET, and will fly home after that game for their first night back in Salt Lake City since a four-game swing through Philadelphia, Toronto, Montreal and Ottawa.
Utah are 10-7-1 with 21 points, fifth in the Central. St. Louis are 7-8-2 with 16 points and were sixth before Saturday’s defeat in Nashville. The Blues have lost three in a row, at the Rangers, at New Jersey in overtime and at Nashville, and they host Detroit on Tuesday before travelling.
The two sides split last season’s series 2-2. Utah won 7-4 in St. Louis in October 2025 and 4-2 at home in January, while the Blues won 1-0 in St. Louis in November, with Joel Hofer making 18 saves, and 5-3 in Salt Lake City in April behind a Robert Thomas hat-trick.
That last result is the closest comparison for Thursday: a Blues win in Utah built on Hofer in goal and Thomas finishing. Both are still central to how St. Louis play, and Hofer’s numbers this season are the best of any goalie likely to appear in this game.
Utah Mammoth: 3.50 goals for, 3.50 against and an .870 save percentage 
Utah have scored 63 goals and conceded 63, an average of 3.50 each way. Seven of their last ten games have produced at least seven goals, including a 6-3 defeat at Philadelphia on 1 November and a 5-4 overtime win over Tampa Bay on 24 October.
Clayton Keller leads the team with 24 points, 19 of them assists. Logan Cooley has 11 goals and 21 points, while Mikhail Sergachev (20 points from defence) and Nick Schmaltz (nine goals, 20 points) give them four players at 20 or more. That depth goes a long way to explaining the 37.1% power play.
The goaltending hasn’t kept up. Karel Vejmelka is 6-6-0 with an .870 save percentage and a 3.29 goals-against average in 13 games, and Sebastian Cossa is 4-1-1 at .871 and 3.30. Both sit nearly 50 points of save percentage below Hofer’s .918 at the other end.
The road trip finished badly. Utah won 3-2 in Toronto on 3 November but then lost 5-4 in overtime in Montreal and 4-2 in Ottawa on Saturday. At home, they’re 4-2-0, the stronger of their two splits.
The blue line is short-handed. Maveric Lamoureux had shoulder surgery and is out for four to six months, John Marino is on injured reserve with an upper-body injury, and Nate Schmidt missed Saturday’s game in Ottawa. Kailer Yamamoto is also on injured reserve up front.

St. Louis Blues: three straight defeats, but Hofer at .918 and an 85.7% penalty kill 
Joel Hofer is 6-4-1 with a .918 save percentage and a 2.39 goals-against average. Jordan Binnington, by contrast, is 1-3-1 at .851 and 4.27, so the Blues’ results have tracked closely with who starts in goal.
The penalty kill has been a strength, working at 85.71% through the first week of November. Against a Utah power play that has scored 23 goals, that’s the matchup most likely to decide the night, and it’s one of the few areas where St. Louis rank clearly ahead of their opponents.
Scoring is spread thin. Jimmy Snuggerud leads with eight goals, Philip Broberg and Dylan Holloway have 12 points each, and Robert Thomas has 11. St. Louis average just under three goals a game, and they were held to one in two of the three defeats on this losing run.
Form away from home has been poor at 3-6-1. Most of their recent wins came at home: 2-1 against Winnipeg, 6-2 against Vegas and 4-1 against Boston, with a 5-4 win at Detroit on 31 October the exception. The latest road trip brought a 3-1 defeat at the Rangers, a 5-4 overtime loss at New Jersey and the defeat in Nashville.
The injury list is long. Torey Krug is out for the season with an ankle problem, Dillon Dube is on injured reserve with a neck injury for at least eight weeks, and Tyler Tucker had knee surgery with a re-evaluation set for six weeks. Logan Mailloux rejoined the team from a hand injury on 6 November.
Probable lineup Utah Mammoth: Not announced at time of publication. Utah are likely to split Vejmelka and Cossa across the back-to-back.

Free NHL Prediction: Utah Mammoth vs St. Louis Blues
Our prediction: St. Louis Blues to win (moneyline)
We’re taking the Blues. The deciding factor for us is the schedule: Utah play a 10:00pm ET game in Las Vegas the night before and fly home for this one, while St. Louis get a full day between hosting Detroit on Tuesday and this game.
St. Louis have lost three straight and won only three times on the road, and if Utah’s power play gets four or five chances the 37% conversion rate can swing it. We still prefer a team with a .918 goalie and an 85.7% penalty kill against one with two goalies at .870 and .871 who concede 3.5 a night.
The Blues won 5-3 in Salt Lake City last April with Hofer in goal, and Utah’s goal difference of zero suggests their record is closer to average than their points total implies. If Hofer starts, we’d expect St. Louis to keep this tight and take it.

About our free predictions
- What we publish on MathOdds are analyses, nothing more. We share a view, a reading of the moment, but never a guarantee. Sport remains what it is: unpredictable. A red card, an injury, a last-minute goal, and the script changes completely.
- Let’s be clear: there is no such thing as a risk-free bet. Even when it looks “obvious”, nothing ever is. And yes, that means you can lose. It’s even inevitable at some point.
- The smartest approach is to stay reasonable. Bet small, set a budget and stick to it. Never use money you need to live on. And above all: don’t chase your losses: that rarely ends well.
- A bet should remain a game, not a job or a source of income. If it starts taking up too much space in your daily life, causes stress or frustration, take a break. And if needed, talk to a support organisation: that’s what they’re there for.
- Ultimately, responsibility lies with you. Reading our content means accepting that risk exists and will never disappear, no matter how good the analysis.
- Essential reminder: gambling is prohibited for minors and must comply with the laws of your country. Need help? Visit begambleaware.org.
