This is a list of UFAs. (Not up to date because they still have Foligno).
I don't want the Flyers to trade any picks/prospects to acquire UFA rights. There isn't one or two on the list that can turn this team into a legitimate contender. I hope they are patient. I also hope they trade 3 of Schultz, Coburn, Grossmann or L.Schenn.
D that will make it to July 1 and will get overpaid are Sekera, Petry and Franson. Question is, do you want to give any of them a MacDonald like contract? I don't.
Guys like Boychuk and Staal will be resigned prior to July 1.
There might be more interesting names available in 2016 and by then the Flyers will know what it takes to resign Jake, Couturier and B.Schenn, as well as knowing whether both RJ and Vinny need to be bought out.
They aren't contending next year, so I would go for Schultz type 1 year contracts and allow space for the young D prospects.
EDIT: I do worry that Mr. Snider will see that two D acquisitions made the Isles into a contender and put the pressure on again though.
