Sounds about right, he's going to be a middle-six guy for the Flyers. Watching the WJC pre-elimination game of Canada vs. Sweden, he looked very good. It's always the same compliments. Compete level, board work, nice hands.
Yeh, he was rated a late 1st, early 2nd going into draft year, but fell due to concerns over his speed (he was always a fair 'skater' as his edgework and balance/lower body strength was always fine), and that he did not 'dominate' in the J20. But his speed has really improved (he will never be a 'burner' but you would not say his skating is something that needs proper 'work' any-more) and he can now beat people on chip and chase and in short burst speed battles.
I think in a re-draft he goes ~25-40.
His SHL production for his age means he is very, very likely to be an NHLer... get ~25+ points at that age in the SHL and you are an NHLer.
The great think with him as well is he is so well rounded... it would not be surprising to see him carve out a role as a 2nd liner (~45-50 points, PP net-front in a 'reverse Simmonds' role (as a lefty))... but also would not be surprising for him to carve out a role as a bottom sixer either.
Very smart player who does all the little things, you can probably count his 'mistakes' in his SHL career so far on one hand, and that would not be a great exaggeration.
He is already the guy who is the defensive minded winger, physical/net-front presence and board-work guy on the best line in the SHL.
Will be interesting do see how he does if he comes over to the AHL next season... I would expect a ~Kempe level impact (Kempe has better physical tools but I think Lindblom is a better defensive player and slightly 'smarter'.) and ~50 points.
