so what is his upside exactly?
He reminds me of Zednik a lot. Quick, physical , can score but lacks vision.
My view on Kulich might be different than the popular opinion, but I hope he is developed as a shutdown center.
I've liked him more as a center than a winger, as he was very good defensively while playing center in Czech league. Might very well be the most impressive defensive play by a center that I've seen from anyone in this draft. But I think his limited playmaking ability and mediocre puck control will hamper his ability to contribute offensively, and because of that I'm not sure how well he would do in a offensive top 6 role.
I think great outcome for him would be Eriksson Ek type of center, i.e. a great shutdown center in a middle 6 line. Kulich and Eriksson Ek share quite bit of similarities as prospects. Strong skaters, hardworking, responsible and offensively their best asset is shot/goal scoring. At the same age I'd say kulich is slightly better skater and has better one timer, while Eriksson Ek was slightly bigger, stronger and had better puck control, at least as far as I remember. Both lack a bit in skill and creativity which is the reason they do better in a simple straight forward brand of hockey.
Kulich's ability to one time the puck might give him the edge in being able to transfer his goal scoring by shooting to the NHL, which is something that Eriksson Ek has struggled with. This also makes Kulich more appealing option for a PP role. It's possible that kulich could do well in a offensive line, but imo in this case his wingers should be the primary play/scoring chance drivers and kulich would be the workhorse and triggerman for that line.
So, I think his upside is a shutdown center who will not score a ton on 5v5 but will make sure to outscore his opponents, and because of that he is able to play big minutes even on 5v5. He could also play an important role for PK and PP units. And that is a lot of value, and because of that imo he is worth a top 20 pick in this draft. And I hope he doesn't play CHL next season..
