Unlike Sacha, Perron, and OMac, most of Minnesota’s core has local ties to their program. I would be really surprised if one of their core players hit the portal unless Bob is canned (he won’t be). The grass would not be greener for them, imo.
Blue bloods generally do not lose players to the portal unless it’s off-ice issues or coaches being fired. Sacha probably stays if Berry is still here. With the other two, there probably was more to the story than the public is aware of.
