I personally think that Koivu will take a step back this year as i think Grandlund will take a much bigger role. Both Johnson and Kuznetsov could be playing with a top 2 goal scorer in the league, but neither is a guarantee to do so. However, with me in drafts, I almost always lean towards the guy who is the more 'sure thing'. If Koivu plays a full season, I think his average, would be just below either of those players maximums. Both players should be tempting, but keep Koivu, he will be setting up Vanek all year.
