The one thing Bill Guerin can’t control in assembling his Team USA Olympic roster? Health.

Injuries to Connor Hellebuyck, Auston Matthews, Jack Hughes, Charlie McAvoy, Jaccob Slavin and J.T. Miller, plus the fact that we await the Tkachuk brothers’ returns from injuries (Brady on Friday, Matthew next month) — does it all keep Guerin up at night?

Not really, the Minnesota Wild and U.S. Olympic general manager says.

“I know enough about where they are that I have comfort they’ll be ready,” Guerin told The Athletic when asked about the injured players. “What I worry about is someone getting injured closer to that time.”

Of utmost importance, of course, is knowing that his No. 1 goalie from the 4 Nations Face-Off will be back in plenty of time. Hellebuyck, the reigning Hart and Vezina Trophy winner, is out four to six weeks after undergoing a minor arthroscopic knee surgery over the weekend.

“I’ve talked to who I need to talk to, and I’m very comfortable with where Connor is at,” Guerin said. “I’m confident he’ll be OK.”

Team USA named Matthews, McAvoy, both Tkachuks, Jack Eichel and Quinn Hughes as the team’s first six players in June. Now comes the tough part, with five weeks to go before filling out the rest of the 25-man roster ahead of the Dec. 31 deadline.

The decisions aren’t getting any easier with so many U.S. players putting up numbers.

“Guys are making it hard on me, which is great,” Guerin said. “That’s what you want. But in the end, you have to do what you think is best. The worst part about it is telling people they’re not going. Because they’re good guys and good players. There’s so many guys that could be on this team, but we just can’t take everyone.”

Guerin was in Buffalo on Sunday afternoon for the Hurricanes-Sabres game, presumably watching World Championship gold medal hero Tage Thompson a day after being in Montreal for Leafs-Habs, where he had Cole Caufield and Lane Hutson to check in on.

My guess is Thompson would be in if the roster were announced today. Caufield, I think, remains on the outside looking in, but he’s doing all he can to make it hard on Guerin to pass him over.

“I have no issues with his game,” Guerin said. “He competes like crazy. He’s dangerous offensively. It was good to see him play live again.”

Aside from Caufield and Thompson, forwards like Jason Robertson (notably first in points among U.S.-born skaters this season), Logan Cooley (career-high four goals Monday night), Clayton Keller (played very well at worlds in leading Team USA to gold), Cutter Gauthier, Alex DeBrincat, Nick Schmaltz, Troy Terry, Matthew Knies and Alex Tuch are pushing to gain entry after not making the 4 Nations.

“He’s doing all he can,” Guerin said when asked specifically about Robertson. “And again, these are situations where I know guys want to make this team and guys want to be in this situation. There’s a number of players that we could take that we won’t end up taking because we won’t have the room. And when you look at it, there’s so many guys that are close in the way that they’re performing, in their statistics, in their body of work. It could come down to the fit. What do we need?’’

Just like with Team Canada, there are two very important things to remember with the Team USA process.

The first is what was learned at 4 Nations, as far as how hard and heavy the game was — how little free ice there was at best-on-best. That is absolutely influencing roster decisions for Milan, where the game will also be played on smaller NHL ice.

“Honestly, I just don’t think you can put into words how tight those games were (at 4 Nations),” Guerin said. “How little room there was to operate. And how well these elite players can check. In NHL games, they’re not always counted on to do that, but when they are, they can. And not everybody can play in those situations. No matter what their offensive gifts are, if you can’t check, it’s probably not the tournament for you. … There’s just no room out there.’’

The second thing to remember is that it matters if a player was at 4 Nations. Team USA lost a coin-flip championship game in overtime to Team Canada. Guerin liked a lot of what he saw there.

“That definitely plays in their favor, the experience of it,” Guerin said. “We had good chemistry on that team.”

Which is another way of saying a player’s history is important. It’s not just about looking at current form.

“I’m a big believer in body of work,” Guerin said. “I appreciate the first two months of the season, but I’ve said this before: this is not Pee Wee tryouts. This is not, ‘Oh, just take who’s playing well.’ If you did that, you wouldn’t need a general manager or coaches. We’re actually trying to build a team.”

If one were to read between the lines — and to be clear, Guerin did not mention names in this way — the body-of-work case versus current-form case would help J.T. Miller keep his spot on Team USA despite his offensive struggles this season. He kills penalties and was an important faceoff guy at the 4 Nations.

So Team USA’s final roster may upset fans who wanted more fresh faces. There will be some new players, but I don’t think it’s going to be a long list.

Guerin met with the Team USA management group on Nov. 10 in Toronto and plans to do so again before the Dec. 31 deadline, in person during the holidays, “to put the final roster down.”

Five weeks to go. It’s crunch time. Guerin’s message to his Team USA management group?

“Dial in,” Guerin said. “See as many of these guys as we can. Give everybody a fair shot at it. Then we’ll make our decisions.”
