Through 14 games this season, he's checked pretty well all those boxes.
"You have to be ready for anything," said Gagner. "It's a long season, there are going to be ups and downs, injuries, different things that happen. You have to prepare for any role. Whatever is asked of me, I'll do."
As far as Appleton's penalty killing duties go, Bowness said there will be a slight adjustment. Usually, the Jets begin the penalty kill with Appleton and Adam Lowry.
That will change to Lowry and Axel Jonsson-Fjallby.
"Then (we'll) come back with (David Gustafsson) and Saku (Maenalanen) sitting there," said Bowness. "And (Dominic Toninato) will play tomorrow and (Blake Wheeler) and KC and Mark - they've all killed penalties."
LINE RUSHES
After not skating with the main group on Tuesday, both Connor Hellebuyck and Dylan DeMelo were back with the team on Wednesday.
The full line rushes looked like this:
Connor-Scheifele-Gagner
Perfetti-Dubois-Wheeler
Jonsson-Fjallby-Lowry-Eyssimont
Toninato-Gustafsson-Maenalanen
Harkins
Morrissey-Pionk
Dillon-Schmidt
Samberg-DeMelo
Capobianco
Gagner's promotion to the top line left a spot open on the right wing with Lowry, one that Bowness has slotted Mikey Eyssimont in for now.
Eyssimont played his second NHL game on Sunday against Seattle, totalling 8:11 of ice time and one shot on goal.
"He showed a lot of good, positive things in the Seattle clips, and he was in a lot of them," said Bowness. "He's fearless. He's quick. He's on the puck and he's not afraid to shoot the puck, which we love. He was putting pucks on the net. And what he showed us during that game was that he was reliable without the puck."
BIG NIGHT
There have been many memorable nights in a Jets jersey for Blake Wheeler, but rarely do those memories involve the opponent more so than his own team.
That rare case came when Teemu Selanne returned to Winnipeg during the 2011-12 season as a member of the Anaheim Ducks.
"It probably was one of the loudest crowds we've had," Wheeler said. "Obviously the nostalgia of that year in particular, it was probably a lot of people's fondest memories of the Jets, either version. He was here for a short time, but he made a huge impact and had one of the greatest seasons in the history of the league in this city wearing our uniform."
