The Toronto Maple Leafs are switching things up.

Fresh off a disappointing 7-3 loss in Game 1 of the opening round of the Stanley Cup playoffs against the Tampa Bay Lightning, the Leafs revealed a fresh set of forward combinations at today’s practice.

The Leafs were favoured to win the series when lines opened as per Sports Interaction, though Tampa has overtaken those odds by virtue of their 1-0 series lead, at odds of -132 compared to Toronto at +116.

"I don't think nerves had anything to do with why we don't defend our net and allow a guy to walk out from below our goal line. Those are all things where we are as good as anybody in the NHL at defending that area of the ice. It didn’t happen tonight," Leafs Coach Sheldon Keefe said of if Toronto felt nervous heading into last night's game.

"That is disappointing, but I think it would be too easy to chalk it up to nerves at this point."

Per TSN's Mark Masters, here's how the Leafs lined up at practice today.
