After the Toronto Maple Leafs fired head coach Mike Babcock on Wednesday afternoon, all eyes turned to the man who took his spot — Sheldon Keefe. The new Leafs bench boss makes his NHL debut on Thursday night in Arizona — with the lofty expectations of ending the team’s six-game skid. However, Keefe will not only have the comfort of more than a handful of players on the roster that he has coached in the American Hockey League with the Toronto Marlies, but he’ll also have general manager Kyle Dubas firmly in his corner. Dubas and Keefe go way back, to the days of junior hockey. April 15, 2011Kyle Dubas, 25, is hired as the general manager of the Ontario Hockey League’s Sault Ste. Marie Greyhounds — the second-youngest GM in the history of the OHL. Dec. 3, 2012Sheldon Keefe is hired as the head coach of the Greyhounds mid-season when Dubas fires Mike Stapleton.

They would go on to lose four straight games to a stacked Erie Otters squad in the second round.July 22, 2014Dubas is hired as an assistant GM with the Toronto Maple Leafs. During his tenure at the Soo, 14 players were drafted to the NHL — the second-most among OHL teams during that span.Then-GM Dave Nonis noted, “He is an innovative thinker that will bring enthusiasm and impressive abilities to our club. His work ethic, character and demonstrated leadership in Sault Ste. Marie, make for a valuable combination that will certainly have a positive impact on our organization in many ways.”2014-15 seasonWith Dubas now in Toronto, Keefe undertakes his second full season in Sault Ste. Marie — and it was a benchmark year for the coach. The Greyhounds won the Hamilton Spectator Trophy with the best record in the OHL (54-12-0-2, 110 points) for the first time since 1985; it was also a then-franchise record.

Keefe left the Greyhounds after compiling a 98-29-2-7 record in his two full seasons behind the bench while earning the 2015 OHL and CHL Coach of the Year trophy. 2015-16 seasonWith Keefe at the helm, the Marlies ran away with the regular season — finishing first in the North Division (54-16-5-1) and winning the Macgregor Kilpatrick Trophy for the team that finishes with the most points in the AHL. The trophy was a first in the franchise’s history as it had the third-best record in AHL history; however, the Marlies lost in the conference finals .Keefe coached several current Maple Leafs that season, including forwards William Nylander, Zach Hyman, Kasperi Kapanen, Frederik Gauthier and netminder Kasimir Kaskisuo.2016-17 seasonWhile they started off the season 6-1-1, the Marlies fell slightly short of the previous season’s record-breaking numbers.

Once again the Marlies saw themselves atop the AHL standings, capturing another Macgregor Kilpatrick Trophy with a 54-18-2-2 record. Feeding off a monster year from Garret Sparks — who won the Aldege “Baz” Bastien Memorial Award as the AHL’s best goaltender — and Johnsson, the playoff MVP, the Marlies won the Calder Cup.They needed seven games, but the Marlies won the first men’s hockey championship in Toronto since the Maple Leafs won the Stanley Cup in 1967; the Toronto Furies won the CWHL title in 2014.
