Few figured coach Ralph Krueger could transform the Sabres so quickly that – gasp – a playoff berth would feel possible this season.

Players need time to understand new messages and systems. Besides, Krueger inherited a hapless team that won just two games last March.

It would take time – maybe months, even a season – before the Sabres showed real progress, right?

Well, six games into Krueger’s tenure, the Sabres are still undefeated in regulation, a sparkling 5-0-1.

Monday afternoon’s 4-0 win over the reeling Dallas Stars was probably their most complete effort of the young season.
