I hope they give Leivo a real shot this season. I think Grundstrom will eventually be the better player, but no harm in having him on the Marlies for another year.
Small sample size, but Leivo is actually pretty good advanced stats wise 5/5, takes the puck away more than gives it away, he even wins faceoffs when he has to. In fact his only weakness was his relative Corsi on the PP, which only happened a couple of times last season. A perceived skating weakness hasn't helped, but when you are running with gazelles, that's going to happen.
Healthy competition is all he asks, now with JVR gone he should have a fair chance at a left wing spot, whether the coach lets him is another question.
