Yeah, you don't compare #6 year to year.
You compare #6 to the #7, 8, 9, 10 and 11 etc, in his own draft year.
Given the DIRE need for defensemen in this organization, and given that draft had more great defenseman than any in recent memory, and given the value of defense and how hard it is to acquire high level D anywhere but the draft.... to me, Zadina will always be compared to Hughes, Boqvist, Bouchard and Dobson.
There are other defensemen from that draft who might be impressive, like Smith and K'Andre Miller and Sandin and Romanov. But that top 4 group is the one I regret passing over.
