After signing Tavares to a seven-year, $77 million contract, the Maple Leafs are one of the most formidable teams up the middle in the NHL, Babcock said. Tavares (37 goals, 47 assists with the New York Islanders), Matthews (34 goals, 29 assists) and third-line center Nazem Kadri (32 goals, 23 assists) had a combined 202 points last season.
"[Marner] is so quick," Babcock said. "The other side of that is Nylander and Matthews play great together too. When you go through that, we're deep enough that [Kadri] is going to have good linemates too. … When you go up front, we're going to have lots of depth and lots of speed. We'll find real good mixes for those guys.
"We'll see how it goes. They're good players and they want to play with good players. And we want them to play with good players. We're fortunate we have a lot of good players."
Babcock said Tavares would replace forward James van Riemsdyk on the power play. Van Riemsdyk signed a five-year contract with the Philadelphia Flyers on Sunday.
"He'll fit right in there," Babcock said.
Marner and Matthews were among the players who contacted Tavares attempting to woo him to Toronto.
"Auston was very much on-side with this, so was [Marner], so were all the guys," Babcock said. "Our guys, I'm real proud of them, the way they reached out. If you're going to win championships, you need depth. You need lots of depth. That's what they want to do, they want to win. In order to win, you need quality players, and we're real fortunate to add John."
