Willander since world U 18's:
+47 in 57 games (college +international)
Now plus minus isn't the greatest stat but you're doing something right when it's that high. I think a lot of the nuances in his game help him always play a positive role in goal prevention no matter what level he is playing.
He can skate effortlessly, munch minutes at even strength/pk, shut down other teams players, and not take many penalties. I don't know what more people want from him but really the offense should be considered an added bonus.
