I don't think they passed on those two because of "this mindset", I believe JV being a hometown kid played a major role. Never the less theres a big size difference between Debrincat and Ehlers/Nylander.
In fact, JB hasn't been shy about acquiring small players at all and hows that worked out so far?
Are you saying the reason his acquisitions have failed is because of their size? I would say it's because their noticeable lack of skill.
