Let me re-phrase it this way: his draft-year goal scoring suggests that you should not expect him to score a lot of goals at the NHL level (which further suggests he will end up further down the lineup at the NHL level). Your comparison is telling me his goal production stacks up favorably with other first-round picks with limited offensive upside. None of those guys are touted as being gifted offensive players or sure-fire top-six forwards. Perhaps it is all just a matter of perception though.
Veleno isn’t going to be a goal scorer, he’s a playmaker. Just because he probably won’t put up 20+ goals regularly doesn’t me he is a 3rd liner, would you say a 10g 70a guy is a 3rd liner? Not saying he’s doing that, but he’s on pace to being a 2nd liner for sure and I think his skill set can be even further than that.
