"The Toronto Maple Leafs are in Vegas tonight to play what is a huge game for the Leafs. Right now the Leafs actually aren't on pace to land a playoff spot and lots of people feel this road trip will decide Mike Babcock's fate. As we learned yesterday, Babcock has decided to switch up his defensive pairings. Jake Muzzin will be paired with Justin Holl and Tyson Barrie will be with Travis Dermott. Upfront, Babcock confirmed Pierre Engvall will make his NHL debut tonight and play on the fourth line beside Nick Shore and Frederik Gauthier. Frederik Andersen will get the start between the pipes. Here's a look at tonight's projected lineups:Johnsson - Matthews - Nylander Hyman - Tavares - Kapanen Mikheyev - Spezza - Petan Engvall - Shore - Gauthier
