"I like the look of this team right now," Armstrong said.
He should, because of how vital center depth is in the NHL.
The Washington Capitals won the Stanley Cup last season with Evgeny Kuznetsov, Nicklas Backstrom, Lars Eller and Jay Beagle, giving them three legitimate scoring lines and a fourth line that could and did chip in. They were comfortable with any matchup.
The Pittsburgh Penguins won the two seasons prior with the same formula, using Sidney Crosby, Evgeni Malkin, Nick Bonino and Matt Cullen down the middle.
The Blues don't have the same star power as the Capitals and Penguins, but they're deep enough, especially with the two-way ability of O'Reilly and Bozak, to be confident they can win matchups at home, where they have the last-change advantage, or on the road, where they don't.
It's even better that O'Reilly and Schenn are lefties and Bozak and Thomas are righties.
"We have balance," Armstrong said.
The key for the Blues was getting O'Reilly because of the impact he has on the game in all areas, especially at the face-off dot and on special teams. Even if O'Reilly moves to the wing to accommodate more ice time for Thomas, he'll still take the bulk of the face-offs.
O'Reilly is 12th in face-off wins (6,261) since he came into the NHL in 2009-10. He leads the NHL in wins (3,337) and is second in percentage (58.3 percent) behind Antoine Vermette (59.2 percent) among 87 players who have taken at least 2,000 face-offs since 2015-16. He won an NHL high 1,274 face-offs (60.0 percent) last season, when he was 62.5 percent (514 of 822) in the defensive zone, 61.8 percent on the power play (210 of 340) and 55.3 percent on the PK (110 of 199).
