A guy gives a valid criticism but oh no, all of the wings prospects gotta be perfect without any flaws, because that's realistic. Athanasiou scored 30 goals but his flaws meant he was still a negative impact player despite scoring all these goals. But for him, it was more than just tunnel vision.
Tunnel visioning is a valid concern and has held many players back in the past. Doesn't mean Soderblom can't improve on that OR be an effective NHLer in spite of that, because if that was his only weakness, that's actually not a big deal but might hold him back from being a true top-6 impact player. That's all.
His potential is enormous, but still has few things to work on. Absolutely nothing wrong with pointing that out.
