HF is not a credible source. It is clear by anybody that reads their site that its ran by a bunch of hockey dorks with nothing more than theoretical knowledge and narrowmindedness to offer. The guy that wrote that piece surely hasnt watched Hickey play enough to make that statement, and I really wouldnt be surprised if he hasnt watched him play regular season hockey at all.
Bleacher Report's blurb isnt really saying anything new that we dont know already.
The fact is that he is still a young player. The guy had some injury trouble to start his pro career in a defensive minded organizationm already with many high picks and depth. I think with a change of scenery(preferably to an organization open to dressing a skilled puck mover, opposed of using 5 defensive Dmen and the whiny Doughty), Hickey can be an impact player. Maybe not '4th overall' impact, but he certainly hasnt peaked.
