I don't think that would help Lundell at all. Lambert's skills are absolutely elite so he belongs in there, but at this point his team and off-puck play are still a year or two away from WJC level. It's pretty unfortunate but with Kakko in NHL, there is no top forwards in this age group for Lundell to work with. Puistola and Aa. Räty were the two I had high hopes for a year ago but that didnt exactly work out
Next year looks to have more depth with a bunch of players returning Aa. Räty, Lambert, Helenius, Hirvonen and Simontaival. Oh and Järventie too. He has been a flop this year but gotta remember he is barely 18.
