Cup teams can afford to have smaller players on their roster, it's not the end of the world if they ice some guys under 6ft.
Tampa won with Kucherov and Point. Colorado won with Makar. Pittsburgh won with Crosby and Guentzel. Hawks won with Kane. And I'm just listing off the more significant players under 6ft on those teams, all of those teams generally iced at least a few smaller guys.
If you are drafting size, you are passing up a lot of talent. I don't know Verbeek's drafting method as well as Ducks fans, but I do know he is/would be an idiot to pass up going BPA just because he has a size fetish.
