Stanley Cup contenders aren’t waiting until the NHL trade deadline day to shore up depth for what they hope is a long playoff run. The league-leading Florida Panthers got deeper on the wing by acquiring Vladimir Tarasenko from Ottawa. Connor McDavid’s Edmonton Oilers added a pair of centers in Adam Henrique and Sam Carrick from Anaheim. The New York Rangers added a player they coveted in Alexander Wennberg from Seattle. And Colorado loaded up by getting defenseman Sean Walker from Philadelphia and center Casey Mittelstadt from Buffalo. There is plenty of speculation the Penguins will move forward Jake Guentzel before the deadline.
