Yes, very much so.
Leafs are moving from an East-West figure skating rush team, to a North-South physical heavy style dump and chase team starting with their new coach appointment.
You require completely different player personnel to play regular season pond hockey and winning playoff hockey as we have witnessed painfully with easy outs in round #1.
"Regular season Warriors, and Playoff Paper Tigers" is the way I have described this,
That is in fact a strategy for BT to now provide Berube the types of players to successfully play his system and allow the team to potentially play playoff style hockey starting at game #1 of the regular season, and not flip a switch come playoff time going from run and gun to dump and chase.
Different style players = Strategy.
