The Philadelphia Flyers will likely be sellers at the NHL trade this year, and it's not because they're rebuilding. 

They've just had disappointing failure of a season and will need to make some changes for next season. 

Among them, Wayne Simmonds is likely on the way out, but could be on the way in?

NHL insider Bob McKenzie says the Flyers will still be looking for a starting goalie along with a top four defenseman and top two or three center. 

It's going to be interesting because Simmonds will likely be dealt to a Stanley Cup contender, but would they be willing to give up any of those things to in the middle of a playoff push?

General manager Chuck Fletcher definitely has a challenge ahead of him.
