Virtanen strikes me as the type of player who will likely always be a little overrated in terms of corsi. Corsi is one of those stats that works decently in general, but there will always be players who buck the trend a little. Guys who are less creative and tend to take a lot of shots from everywhere are going to look better than they are and I question how much of an accurate determination of possession it really is for him if you had date for actual zone time. He does look like he's starting to take a bit more time to make a creative play with the Sedin's though which bodes well.
