Although centers are more wanted than goaltenders, it's been difficult for the Jets to find the right team to trade with. Most teams have already finished signing free agents and setting their rosters, so there aren't many options left for Scheifele to go to.
There are also a few other teams that might be able to work out a trade. The Nashville Predators are going through some changes but still want to make the playoffs, so having Scheifele on their team would be a big help.
The Columbus Blue Jackets don't have strong centers, so having a reliable top-six center like Scheifele would improve their forward group. As for the Ottawa Senators, if they decide to part ways with DeBrincat, having a player like Scheifele for a season would be a good option.
