He saw how that could work at the 2021 WJC when he coached the United States to a first-place finish.
Now he hopes to help the United States win consecutive tournament titles for the first time.
"Your team has to come together, love one another and buy into the roles, buy into the sacrifice of what it takes to be successful in the tournament," Leaman said. "That's one thing that came through throughout 2021, was how much that group really cared for each other. We're hoping to build that same chemistry with this group. I can tell you, we've been talking about it a lot."
The 2022 WJC will be held Dec. 26 to Jan. 5 in Edmonton and Red Deer, Alberta.
The United States has won five times (2004, 2010, 2013, 2017, 2021), but never consecutive titles.
The team, consisting of three goalies, eight defensemen and 14 forwards, is training in Red Deer, where it will play its preliminary-round games in Group B at WP Centrium.
Also in Group B are Russia, Sweden, Slovakia and Switzerland.
