Given the fact there is a good chance the Maple Leafs will once again face the Tampa Bay Lightning in the Stanley Cup First Round, the strength at center will be key. The Lightning boast one of the best group of centers in the League in Brayden Point, Steven Stamkos and Anthony Cirelli, so the addition of O'Reilly has Toronto in better position to offset what was a distinct Tampa Bay advantage in their seven-game victory in the opening round last season.
Keefe has 24 games remaining before the postseason to tinker, and that includes how to deploy Acciari.
The 31-year-old has been a disruptive force with his physical play and his penchant for going into the greasy areas in front of the net. That style produced his first goal with the Maple Leafs in a 5-3 loss at the Chicago Blackhawks on Sunday and has sent a message to the team's other bottom-six forwards that there will be competition for playing time.
Suddenly, Toronto has the type of versatility in its lineup that Keefe hasn't had since replacing Mike Babcock as coach on Nov. 20, 2019.
He said he couldn't sleep after the trade was made official late Friday. The new possibilities involving various line combinations, he said, danced through his head and kept him awake. By Saturday morning, when O'Reilly and Acciari were on a flight from St. Louis to Toronto, Keefe was meeting with Tavares about shifting to wing.
Tavares, to his credit, was all in, a team-first decision from a player who has spent most of his 1,007-game NHL career at center.
Prior to the victory against the Sabres, Tavares said he felt the line was "getting close" to clicking after being together the previous two games. He proved to be prophetic.
Just 7:14 into the game, the Tavares-O'Reilly-Marner line had already combined for nine points (three each) and was responsible for all the scoring en route to a 3-0 lead. O'Reilly opened the scoring with his first two goals with the Maple Leafs, those coming 37 seconds apart, and Tavares extended Toronto's advantage 2:46 later.
For Keefe, who watched O'Reilly (two goals, one assist), Tavares (one goal, two assists) and Marner (three assists) rocket his team out front like that before the first period was even half over, the lineup experiment could not have gone any better.
"That line, and our team in general, our team game in that first period, that's as dominant as we've been all season long," he said, adding later that "as I said to the guys, that's what we're supposed to look like."
Thanks in part to the captain buying in.
"Each and every game, I'm feeling better and better," Tavares said of his position change. "A little less thinking. It just becomes a habit and instinctive."
Tavares said the biggest difference for him between wing and center is there now requires more time in puck battles along the boards. Judging by Tuesday, so far, so good.
Earlier in the day, Keefe had said the shift of positions was not a one-off; that he wanted to see how the unit jelled. Ten hours later, he left the door open.
"I still feel, at the end of the day, we're going to have John at center," he said.
Maybe. But when? And for how long?
Thanks to the addition of O'Reilly, it's a pleasant dilemma for the coach to have.
