I picked Morgan Reilly.
Big assumption on my part cause he has not really played any meaningful games in the NHL.
I think he'll end up being a more all around D player. He has the ability to carry the puck and also can play some effective D. We'll have to see if he'll be able to transition his game into the faster and tougher NHL.
However, I'd only trade Gardiner once it appears that Morgan has what it takes to be an NHL player. And, I'd only trade Gardiner for whatever we need at that time that gets us some top notch value, otherwise, I keep them both.
