Yeah, IMO this is why guys like Marino and Brunicke seem so much better than expected. The first hurdle to being an NHL D is understanding your best option quickly and not making big mistakes. You can be a solid middle pairing NHL D if you can skate and make outlet passes and do that hyper consistently. Someone that can't process their best option instantly is going to have a hell of a time sticking no matter what their tools are. That's how you get guys that can play keep away for 30s but always seem to end up getting turned around and giving up the puck in bad spots.
