They were the better team in his NHL coaching debut, a 3-1 victory against the Arizona Coyotes at Gila River Arena on Thursday. The same could be said for the first period against Colorado when Toronto built a 4-1 lead Saturday.
But the Maple Leafs reverted to some poor habits in the final 40 minutes against the Avalanche. They were outshot 29-13 and often were caught pursuing opposing players in their own zone rather than clogging up the slot between the face-off dots, one of the wrinkles Keefe is attempting to introduce.
"I think [we're] just going through the process of changing things up on the fly," forward Auston Matthews said. "So I think it'll be good to get a couple of practice days in before we get on the road again, and kind of dial some things in."
The Maple Leafs will practice Monday and Tuesday before playing the Detroit Red Wings at Little Caesars Arena on Wednesday (7 p.m. ET; SN1, SNE, SNO, FS-D, NHL.TV). Another practice is scheduled for Thursday in Buffalo before a home-and-home with the Sabres Friday and Saturday.
Keefe is attempting to get a buy-in on a completely different system from Babcock's. At the heart of Keefe's vision: puck possession and an emphasis on skill. High-risk stretch passes are out; low-risk, multiple give-and-goes are in.
"The toughest thing to grasp is just when to hang onto the puck for a little bit longer than you normally would and when to move it quickly," Keefe said. "When to utilize speed and just look at things on the ice. That's the difficult part, is that decision making.
"I think we have players with really good hockey sense, really good skill and, in time, they'll recognize the patterns, recognize the pressures that are coming at them. Also recognize the time of the game, the time of the period and what's happening in the shift. All of those types of things I think we'll be able to talk them through until they recognize it."
If players need convincing that Keefe's philosophy can work, they need only look at how he has already positively influenced defenseman Tyson Barrie.
