The Ottawa Senators coach said Spezza must not only improve his offensive play, but also his face-off percentage, in Game 3 of the Stanley Cup final against the Anaheim Ducks on Saturday.
Jason Spezza lost 13 of 16 draws over the first two games in Anaheim, Calif.
"He's a guy I believe will have a big turnaround on home ice," said Murray. "I think he'll win face-offs and play better."
The top line of Spezza, Dany Heatley and Daniel Alfredsson was held without goal, and has been on the ice for both of Anaheim's game-winners in the best-of-seven series.
"I know I have to be good for us to start a comeback," said Spezza. "Hopefully I can pick it up at home. I know I have to be an impact (player). When you're a centre on the top line you have to make plays."
The Sens held a light practice Thursday night at Scotiabank Place after flying all day from Anaheim.
