I think his ceiling is the highest of any of our prospects (he still has #2 potential even if it is unlikely) and I think he is an NHL level defender right now. I get his IQ concerns to being more than a #4, but I if he had the right mentor he could round out some of his errors to become a #3. I think the difference between him being a #3 and #4 is cleaning up his own end and decision making defensively. His speed, stick skill and offensive ability all help to make him the top defensive prospect and I personally buy into him as much as Behrens. Size and speed allows for a lot more wiggle room.
