Perhaps I'm overrating him a tad, but Zibanejad looks like the ideal second-line centre to me. Great speed and defensive instincts, but with the goal-scoring talent and finishing ability to post up to 60 points. All while being a Selke-quality defensive forward.
That has a ton of value to a post-season bound club like Tampa Bay looking to shore up their top six. And given the fact that Drouin is the best asset that Yzerman has at his disposal, and the fact that the Lightning have a limited window in which to win a championship with Stamkos' almost certain impending departure, you have to believe that trading him for another high-quality young player who has proven himself more at the NHL level would be quite a nice return for them.
