With Sean Couturier and Hayes at center on the top two lines, it allows Patrick to play in the middle on the third line, where he could see more favorable matchups.
The Flyers' quest to improve their penalty-killing, which ranked 26th in the NHL last season (78.5 percent) could receive a boost from Hayes and defensemen Matt Niskanen, acquired in a trade from the Washington Capitals for defenseman Radko Gudas on June 14, and Justin Braun, acquired in a trade from the San Jose Sharks for two draft picks on June 18. Ivan Provorov, their No. 1 defenseman, remains unsigned as a restricted free agent.
Philadelphia should benefit from a full season with Hart, who was the sixth of an NHL-record eight goalies to start at least one game for the Flyers last season. He went 16-13-1 with a 2.83 goals-against average and .917 save percentage in 31 games as a rookie.
"We've got some good players," Vigneault said. "I'm very confident that we'll be able to find a system there that's going to maximize what we have and make sure our power play and penalty-killing are one of the best in the League."
Melding the newcomers and holdovers starts with training camp, some of which will take place in Europe. The Flyers open their regular season Oct. 4 against the Chicago Blackhawks at O2 Arena in Prague, Czech Republic, as part of the 2019 NHL Global Series.
"It's a group of 25 guys traveling to a different country, you spend a lot of time with each other," said Hayes, who had an NHL career-high 55 points (19 goals, 36 assists) in 71 games with the Rangers and Jets last season. "Inevitably, I think you're going to start communicating with more guys. In order to be a successful team, you have to have a tight-knit group. I've heard that the Flyers have that, and they have a bunch that have been together for a while, and I'm excited to get things going."
