Turnovers have been an issue for the Canadiens the entire series and the Lightning keep scoring goals off them.
The last time they played here, Game 2, the Canadiens played arguably their best game of the series, outshooting the Lightning 43-23, but Tampa Bay scored two goals directly off turnovers and won 3-1.
Tampa Bay's two goals in Game 4 came directly off Montreal turnovers.
"You play against good players, if you fuel them with giving them pucks and making it easy on them, they're going to find solutions," Ducharme said. "But that's something that we know. We know how to do it. It's not a matter of putting us on our heels at all, it's just recognizing situations and knowing our options and what we want to do. Guys know. We know how to do it. Our execution was better last game and it's going to be better tonight again."
