"And the game has definitely changed since I coached it last," he added. "…It's a fast, fast game. It's more attacking driven."
If there's anyone in the game that has seen it all, done it all and is capable of adjusting to it all - it's MacTavish.
The 64-year-old London, Ontario native put together a 17-season playing career in the NHL. His name can be found on the Stanley Cup four times - he won three championships with the Edmonton Oilers (1987, 1988 and 1990) and one with the New York Rangers (1994).
His playing career that spanned 1,093 regular-season games and 480 points (213 goals, 267 assists) would wrap up with the St. Louis Blues, where he retired in 1997. MacTavish then turned his sights on coaching, joining the Rangers as an assistant that same year. He took over as the head coach of the Oilers from 2000-09, helping Edmonton to the postseason three times in that span, including in 2006, when the club reached the Stanley Cup Final for the first time in 16 years.
After his head coaching tenure was done with Edmonton, he also was brought back to serve as the general manager of the Oilers from 2013-15.
"Obviously you look at the number of games 'MacT' has coached... there's really nothing we're gonna see moving forward that he hasn't dealt with," Blues General Manager Doug Armstrong said after hiring MacTavish as a Blues' assistant coach in the offseason. "He reminds me a lot of (Hockey Hall of Famer) Larry Robinson in that way, in the sense that just when he walks into a room, the room gets brighter. The knowledge of his four Stanley Cups and coaching, managing, being in every aspect of the game - he's gonna be someone that I think everyone's really gonna enjoy working with from the coaches to the players and trainers, and everyone around our group. I think this could be a really good marriage."
