It is certainly getting crowded down in Grand Rapids. I have to imagine some of them will fill spots vacated by pending free agents:
Hamonic (obviously don't need him back)
JVR (faded hard down the stretch after providing some nice depth at first)
Perron (he's old even if I love his attitude)
Kane (I can take or leave him, it is nice to have him on the PP, maybe they re-sign him another year partly in hopes it helps DeBrincat extend)
Talbot (Just bring up Cossa already)
Wallinder should be up unless he looks absolutely awful in camp, he has to go through waivers and someone would claim him. I don't see any other defenders down there making the jump. Buium's skating seems to still not be NHL level from what I see, I would be shocked if he's ready but I'm often wrong. Anton Johansson is an interesting wild card but still probably gets an AHL year.
Danielson, MBN, and maybe Lombardi have a chance to make the team I think for the forwards. Probably not all of them. The NHL free agent class is absolutely awful so I don't know what the Wings will do with a decent amount of roster spots open. I wouldn't mind shooting Rasmussen into the sun to make further room too.
