Morrissey returned from a lower-body injury and scored one of Winnipeg's three power-play goals, and the Jets got goals from seven players while routing the Philadelphia Flyers 7-1.
''I woke up this morning, felt awesome, came to the rink and went through the routine and everything was good to go,'' said Morrissey, who extended his point streak to three games.
Winnipeg weathered an early Philadelphia push, as the Flyers outshot the Jets 10-1 through the opening seven minutes, and 17-6 in the first period.
''Some nights you come out super hard and all of a sudden you start to lose momentum as the game goes on,'' Morrissey said. ''Some nights it looks like tonight.
''Once we started skating and getting on the forecheck and putting more pucks to the net - when we do that we can get second and third opportunities and get some zone time, and we started to roll.''
Jakub Voracek scored his eighth goal for the Flyers (12-13-3).
''We were dominating in the first,'' Voracek said. ''Hellebuyck was standing on his head. He was playing pretty well. When they scored that third goal we kind of, I wouldn't say (we) changed things a whole lot, but we just tried to make the plays that weren't there.''
The Jets' power play was 3 for 6, while the Flyers went 0 for 2.
Connor Hellebuyck made 36 saves for Winnipeg.
''It's tough coming back when you haven't played much hockey, really it's over the last 10 to 12 months,'' Flyers coach Dave Hakstol said of Neuvirth. ''Obviously, he wasn't seeing the puck. That's a tough first outing.''
Connor's shot from the high slot found its way through traffic for his 11th of the season to open scoring for Winnipeg midway through the first. It was Connor's first goal in 10 games.
Morrissey struck less than three minutes later with Radko Gudas off for roughing Scheifele. Morrissey beat a screened Neuvirth with a slap shot for his third goal of the season.
Winnipeg scored three times in the second period, with the first chasing Neuvirth as Tanev jumped on a rebound for his fifth goal of the season.
Five seconds into their second power play of the game, Byfuglien's point shot made its way through for his third of the season, making it 4-1 for the Jets.
Wheeler's short-handed breakaway goal late in the second period was the Winnipeg captain's 15th-career short-handed point, setting a franchise record.
NOTES: Philadelphia's Robert Hagg was given a game misconduct in the second period for a hit from behind on Connor.
Flyers: Continue a five-game trip at Calgary on Wednesday night.
Jets: Host Chicago on Tuesday night.
