That's my point.. they haven't ever really been able to get offense out of guys who have had the questionable offensive upside tag. So if we took Broberg or Seider, I wouldn't be confident that we'd get that offense out of them.
But who of these guys you mentioned were developed like bottom pairing D men though? NB had plenty of opportunities. Tinordi was young enough when moved to still be able to get his career on track if the problems were merely organizational. Besides that he just never showed any offence at any level.
Mete's on a top pairing and allowed to rush the puck quite a bit as a 20 year old. Again Juulsen's really only played one pro year. Did he not get any PP time with Laval? Genuinely asking.
The first two is asking to get blood from a stone and the next two don't seem to be actively hampered and are babies one being barely 21 and the other one hasn't even played 2 full years of pro hockey. Christ people think Mete's not an offensive D man yet the guy sure seems to be getting the opportunity to be one.
I don't necessarily agree with the Galchenyuk being actively sabotaged narrative anymore but there's at least somewhat of a case there. I can't even see the case here though. Both Seider and Broberg probably have the highest offensive upside of all the players mentioned (at least at all their respective pre-draft scouting reports). The only one who comes close is NB.
