In need of replenishment at every position, the Detroit Red Wings will gather for three days to explore trades and how to best invest their spare millions.

General manager Ken Holland, assistant GM Ryan Martin, along with Kris Draper and the team’s cadre of pro scouts are scheduled to meet Monday through Wednesday to assess the free agent market and possible trade scenarios.

The Wings estimate they have $20 million in salary cap space headed into next season, but some of that will go to re-sign restricted free agent forwards Tomas Tatar and Riley Sheahan and defenseman Danny DeKeyser.

Of the team’s unrestricted free agents - forwards Daniel Alfredsson, Todd Bertuzzi, Daniel Cleary, David Legwand and Mikael Samuelsson, defenseman Kyle Quincey and goaltender Jonas Gustavsson - almost all are expected to be gone. Holland will be reaching out to the players’ agents following the three-day council. The Wings are waiting to hear if Alfredsson, 41, even wants to play another season, but if he does, there’s interest on their part. As for the others, it’s a good bet Quincey will see what he can get on the open market because UFA defensemen tend to reel in big money, and in Gustavsson’s case, the Wings will have to determine if they’re not better off having prospect Petr Mrazek serving as backup to Jimmy Howard.
