Comment on Dave Hyde: Even as Tkachuk delivered the hurt, Panthers look pained down 2-0

LAS VEGAS — It was a big hit, a ferociously fierce hit, and on some nights Matthew Tkachuk’s open-ice, Zamboni run over Vegas star Jack Eichel might have been the kind to swing a game or define a series. “I just came off the bench and saw him in the middle of the ice with his head down,’’ the Florida Panthers star said, “and it doesn’t matter who you are, you shouldn’t be going through the middle with your head down.” Tkachuk has shouldered much of the load to the Stanley Cup Final, but the attention Monday was on that shoulder, just as the rule book reads, meeting Eichel’s shoulder.
