The Maple Leafs' newest additions now will come from within; Matthews and forwards William Nylander and Mitchell Marner are expected to make the team this season.
Nylander, 20, was the No. 8 pick in the 2014 draft and was leading the American Hockey League in scoring last season when he left to play for Sweden at the IIHF World Junior Championship. Nylander was injured in that tournament but wound up joining the Maple Leafs for 22 games, when he had six goals and seven assists.
Marner, 19, was chosen No. 4 in the 2015 draft and has one year of junior eligibility remaining. He was the Ontario Hockey League most valuable player, the Canadian Hockey League player of the year, and MVP of the Memorial Cup for victorious London. He likely has outgrown junior hockey.
"We're going the right way," Babcock said. "We're not trying to maintain. That maintain part is what kills you. It's not easy to win in this League. But now, and this is no word of a lie, we're loaded with kids. Real kids. There's five or six who are going to score big-time in the NHL."
One of the players Toronto traded, rugged defenseman Roman Polak, re-signed with the Maple Leafs, and they signed 24-year-old defenseman Nikita Zaitsev, who played the past seven seasons in the Kontinental Hockey League.
After a few years of concentrating on acquiring skill, Toronto took aim at adding size and signed free agent left wing Matt Martin from the New York Islanders. At 6-foot-3, 220 pounds, Martin brings an abrasive style and led the NHL with 365 hits (4.6 per game) last season.
The Maple Leafs auditioned a number of prospects last season, including forwards Zach Hyman, Connor Brown, Josh Leivo, Nikita Soshnikov, Kasperi Kapanen and Frederik Gauthier, the No. 21 pick of the 2013 draft; defensemen Connor Carrick, Viktor Loov, Rinat Valiev; and goaltender Garret Sparks. Each is expected to push some of the veterans for a job next season.
Pain, it seems in Toronto, has been replaced by light at the end of the tunnel.
