I've always thought pretty highly of Jankowski. I just thought he would take a while to develop. Not dissimilar to how Blake Wheeler developed.
Big man, took a while to figure it all out. First round pick who went higher then expected.
Now Janko will be a C men rather then a winger (Wheeler) but that is also ultimately more valuable to the team.
I think the idea of a Couturier, Jordan Staal isn't that far fetched.
If Janko can become about as good as a Backlund defensively while being a 6'4" beast with 15-25-40 potential that is a very good player in today's day and age. In 1988 that's a 30-45-75 type player.
