Brayden Schenn is expected to be the second-line center, and Bozak, who had 43 points (11 goals, 32 assists) in 81 games for the Toronto Maple Leafs last season, figures to be the third-line center. The hope is that the Blues will balance out their scoring.
"I think that we're stronger now through center ice," Yeo said. "If you look at your top three as Schenn, O'Reilly and Bozak, we're very comfortable and confident that those guys can play against anybody."
One loss for St. Louis this offseason was goaltender Carter Hutton, who signed as a free agent with the Sabres. Hutton, who split time with Jake Allen last season and played 32 games, led the NHL with a 2.09 goals-against average and .931 save percentage (minimum 20 games).
The Blues signed goalie Chad Johnson to a one-year contract, but Yeo is hoping Allen, who was 27-25-3 with an NHL career-worst 2.75 GAA and .906 save percentage in 59 games last season, can regain his form from 2015-16 when he tied Ben Bishop and Martin Jones for second in the NHL with six shutouts and had a .920 save percentage.
"I expect [Allen] to have a great season," Yeo said. "You look at the age of him relative to starting goalies, he's still very young (28), still learning the position, and with that learning, you know, it's not necessarily the physical part, it's probably more the mental part."
