Surgery on his groin in November has limited Ennis' season to just 44 games, an especially bad break considering he only played 23 games due to multiple injuries last season. He has just four goals and eight assists for 12 points this season, and had seen diminished ice time until being promoted to play on a line with O'Reilly and Jack Eichel in Anaheim on March 17.
Dan Bylsma thought back to Buffalo's game in San Jose earlier this month as an example of what earned Ennis another crack at the top line.
"We saw some spurts form Tyler, getting his jump back and then previously before we went on the road [in California] there were a couple really good examples of him kind of showing what he can do, playing in the offensive zone and dodging and weaving and losing guys with his agility.
"I think you saw that maybe at it's best in Anaheim, playing with those guys, and he's continued that. I thought last night was probably his best game of the year."
With more ice time, Ennis said, comes more comfort.
"Most of us, especially offensive guys, are guys that kind of play better when we get the flow of the game, we get more minutes," he said. "I couldn't ask for better linemates than Ryan and Kyle, two smart players who are reliable defensively, good guys. I thought we had some great jump last night."
Kulikov, meanwhile, came to training camp late due to his involvement at the World Cup of Hockey. After only two days of practice with his new team, a hard hit into the bench door during his preseason debut against Toronto aggravated a preexisting lower-back injury, one that would affect him for nearly the entirety of the season.
Kulikov missed three separate stretches of the season with that injury, time that not only could've been better spent on the ice but also growing comfortable in a new dressing room. He missed another stretch with a neck injury most recently, from which he returned on Saturday to score a goal and an assist.
