Vrana will get an opportunity to play a bigger role with the Red Wings after seeing his ice time dwindle recently and being a healthy scratch against the New Jersey Devils on April 2 and 4. The 24-year-old has scored 25 points (11 goals, 14 assists) in 39 games this season after setting NHL career highs with 25 goals, 27 assists and 52 points in 69 games last season.
Selected by Washington in the first round (No. 13) of the 2014 NHL Draft, Vrana has scored 157 points (76 goals, 81 assists) in 284 regular-season games and eight points (three goals, five assists) in 38 playoff games. He won the Stanley Cup with the Capitals in 2018.
"Anthony and Jakub are both good players, but it is fair to say they are both underperforming their historic statistics," Red Wings GM Steve Yzerman said. "Jakub has been on a very good team in Washington with a lot of talent, so we're hoping he can play a bigger role here on our team and thrive in that situation."
Panik, who has scored nine points (three goals, six assists) in 36 games this season, will also get a chance to play more regularly with Detroit after the 30-year-old cleared waivers and was assigned to Washington's taxi squad April 8.
But the trade was mainly about picking up pieces for the future for the Red Wings, who appear headed toward missing the playoffs for a fifth straight season. Detroit (15-23-6) is last in the eight-team Discover Central Division, 11 points behind the fourth-place Nashville Predators. They next play Thursday at home against the Chicago Blackhawks.
"We are obviously rebuilding our organization and our team, and I felt this was an opportunity to add draft picks, but we still have to put a team on the ice," Yzerman said. "Obviously, we're trying to add draft picks and prospects to expedite the process, but we want to keep our team as competitive as possible this year and next year."
The Capitals acquired Raffl because they wanted a forward who can play wing and center. The 32-year-old scored eight points (three goals, five assists) in 34 games with the Flyers and can be an unrestricted free agent after the season.
"We like our center-ice position, but we wanted a guy that could play there if we needed it in a depth situation or we had an injury or if somebody was out for a few games, and I think he fits the bill there," MacLellan said. "He can play up and down the lineup."
