Despite a lack of offensive production, Ruff said he has no reservations about putting Nichushkin back in the lineup.
"I think every time he steps on the ice he works as hard as he possibly can," Ruff said. "He's been responsible. I think there's always some frustration with not producing. I think if he can get by that frustration he'll be fine."
Dallas recalled forwards Curtis McKenzie and Brett Ritchie from Texas of the American Hockey League on Saturday. Texas was eliminated from the AHL playoffs Friday.
McKenzie had a minus-1 rating and three shots on goal in three NHL games this season, and 31 assists and 55 points in 61 AHL games. Ritchie had one assist in eight games with Dallas and 14 goals and 28 points in 35 AHL games.
In their Game 1 win against the Blues, each Stars goal came off a rebound, the type of goals that result from players being around the net and not being afraid to grind and do the dirty work to either score or set up a teammate.
Stars goaltender Kari Lehtonen, who made 41 saves in Game 1 and is 4-1 with a 2.01 goals-against average and .925 save percentage in five Stanley Cup Playoff games, said getting goals like those is a good sign going forward.
"They're the goals that usually at this time of the year happen," he said. "Nothing pretty, just throw the puck at the net and get rebounds. That's what we need to keep doing, is get a lot of guys in front of the net and then get chances that way."
