Laf annoys me because he looks so bad out there, but people wanting to get rid of Kakko are nuts.
He was the best defensive forward in hockey last year at 19 years old and paced 15 goals over a full season. He's gonna get better. If a guy plays that well in his own end and in the neutral zone and scores 20 you take that all day long. If a guy did that as a 27 year old an hit the open market we'd be talking about a $5-6 mil per year contract.
If you're only acceptable expectation is some game breaking 40 goal scorer then he may not become that, but that doesn't mean you get rid of a guy who is a high quality piece for a contending team.
