I know I'm higher than many on Kakko but, moving Kakko will be a big mistake.
Legitimately shown flashes of being a potential top 15 Selke candidate.
I could honestly see his floor being Jere Lehtonen, while his ceiling is massive imo (think stylistically Peter Forsberg-lite). Do I think he'll score at the rate Foppa did? No probably not, again I said stylistically, but he will eventually cement himself as a very good top 6 RW.
Trading him away for 'cap-clearing' purposes or upgrades elsewhere isn't the route this team should go.
You have to give to get and we obviously need a #2C, but you have to think to our glut at LW/D prospects before you even humor Kakko. I think you even move Fil for the 2C potential upgrade before you move Kakko.
Maybe i'm just a Kakko mark, who knows, but I feel like the majority of the above is grounded. (I SAID FOPPA LITE!!!! and a young Lehtonen is something you don't move either.)
