While he plans on speaking to all of their agents before making any final decisions, the Free Press reports all four may not be back next season.
In fact, the paper claims only Gustavsson has a chance at returning, while the other three, along with Mikael Samuelsson and Daniel Cleary, will not be back.
The Wings may want to keep Quincey, though he could sign for more money elsewhere if he tests the waters July 1.
The only pending UFA that could return is star winger Daniel Alfredsson, who will inform Holland in the near future whether or not he wants to return.
Holland is expected to bolster his blueline this off-season, though with limited options in the free agent market, he could turn to a trade or not in order to improve his defensive corps.
The Wings had shown interest in Vancouver Canucks defenseman Alexander Edler and Buffalo Sabres rearguard Christian Ehrhoff during the season and could revisit talks in the coming weeks.
The Canucks almost traded Edler to the Boston Bruins prior to the trade deadline, but the team reportedly backed out of the deal.
