He is being "heavily overrated" because he:
- Plays a position we are very shallow on
- Plays a style of hockey that we sorely lack
- Will have 6+ years of control
- Is almost NHL ready
Sometimes I think this forum really lacks the ability to consider context. There's a reason Leaf fans are more willing to trade Robertson, who has a more desireable skillset for a lot of teams (scores a lot of goals) than Knies. Of course Chychrun is a better players and the probability is high that Knies will never be as good.
Years on control is also a huge aspect of asset management that most of us casuals don't often value properly.
