"The games have gotten harder, Montreal's played better, and we haven't dealt with it well," Keefe said candidly after Toronto's 3-2 overtime loss in Game 6 at Bell Centre in Montreal on Saturday.
They're running out of time to find a solution. Game 7 is at Scotiabank Arena in Toronto on Monday (7 p.m. ET; CNBC, CBC, SN, TVAS).
The loss was another missed opportunity for the Maple Leafs to win their first Stanley Cup Playoff series since 2004. After building a 3-1 lead in the series, they have lost the past two games and since 2018 are 0-6 in elimination games when they would have advanced with a victory.

Toronto's recent track record in Game 7 adds more angst to an anxious fan base that has seen this movie before. The Maple Leafs have lost their past three Game 7s, all first-round exits to the Boston Bruins (2013, 2018, 2019). They also lost Game 5 against the Columbus Blue Jackets in the best-of-5 Stanley Cup Qualifiers last season.
Keefe said the Maple Leafs are ignoring such history, as difficult as that might be. Instead, they are trying to create some of their own.
"We're not focused on any of the other things that frankly are irrelevant in this moment with our team," Keefe said.
In order for the Maple Leafs to get back on track, Mitchell Marner and Auston Matthews, their best players, have to be exactly that. With one goal between them through the first six games, scored by Matthews in a 5-1 win in Game 2 on May 22, even the normally upbeat Keefe said he needs more from them.
Asked about how he thought the Marner-Matthews-Zach Hyman line performed, the coach didn't mince words.
"I thought they worked really hard," Keefe said. "Obviously they didn't get enough done."
Marner agrees.
The forward led the Maple Leafs and finished fourth in the NHL with 67 points (20 goals, 47 assists) in 55 games this season. Matthews was tied for fifth with 66 points (41 goals, 25 assists) in 52 games, and won the Rocket Richard Trophy as the NHL goals leader.
Marner said the reason success hasn't translated into playoff goals is simple: The line is spending too much time in the defensive zone.
"We need to be better in these situations," Marner said. "We're doing a decent job moving the puck around and getting to the net, but too much energy wasted in our own zone. We're better than that."
