That is tough. I do agree that Stamkos, Seguin, Kunitz are locks. Me personally I always keep a goalie unless they are abundant in your 1st round, which perhaps they are in a 10 man league, for me that locks Crawford.
So I have Stamkos, Seguin, Kunitz, Crawford and then 1 left. Parise is the easy choice however I really like Nichushkin's situation next season so if you do want a RW next season he's who I would roll with, keep both if you don't like keeping Crawford. My preference is to always keep 1 solid goalie.
