If Mike Babcock could turn back time, he’d do things differently.

For the Toronto Maple Leafs coach may have inadvertently created a roadblock for his team while wearing another hat with Team Canada. The decision to put Brad Marchand on the top line with Sidney Crosby and Patrice Bergeron helped him win September’s World Cup, but it’s not looking so good now that Marchand is propelling Boston past Toronto in the Atlantic Division playoff race.

“I shouldn’t have,” Babcock said Sunday, when asked about creating the Marchand-Crosby-Bergeron unit. “I should have played him on the fifth line. Sucked a little life out of him.”

The veteran coach was kidding, of course.

But with Boston due to visit the Air Canada Centre on Monday night it has at least crossed his mind that Marchand’s fantastic season is flowing, in part, out of his strong showing in the best-on-best tournament.

It’s been a transformative stretch for the 28-year-old from Halifax. Once known almost exclusively as a shift-disturbing pest, Marchand scored 37 goals last season and is among the current NHL leaders with 37 goals and 79 points in 71 games this year.
