I personally don't see a SIGNIFICANT offensive game. I think he has the potential to be like a 6'6 Ryan Mcdonagh though, maybe 30-40 points and eating a lot of minutes against top line players. I would rather he had more freedom to try things/ get middle pairing minutes and practise with older players so he can see where he needs to get to strength wise. I think the VHL achieves that the best. Skating around U20 kids all season because its easy for him might provide him with easy confidence but I'd like to see him challenged more.
I also don't think Lokomotiv is just looking at him as a bottom pairing player. You can tell by his usage that they are trying to develop him themselves In my opinion. He clearly isn't ready for the KHL in a large role but they are giving him ice time where they can to give him opportunities without hurting the team (thats why he rarely gets out in the 3rd unless they have a decent lead), they are also sending him down to play full MHL games while still keeping him close to the KHL team (I assume he still practises with main KHL squad).
