The Blueshirts have also received inquiries on Chris Kreider, with the Maple Leafs, Bruins and Predators believed to be three interested parties, but we’re told the winger is only available if general manager Jeff Gorton receives an offer he cannot refuse for No. 20. Thus far, no severed horses’ heads have appeared between the sheets.
Unless the Rangers are simply overwhelmed by an offer including a William Nylander or Charlie McAvoy, trading Kreider in addition to Hayes and Zuccarello would strip the team of three of its four best players (non-goalie division) with only Mika Zibanejad left behind to carry the torch.
