This kid has incredible potential. Watching him pre-benching I was lamenting that if this kid could possibly put on some beef and learn some of the ins and outs of the defensive zone, he'd be unstoppable - and right on cue, he comes back from the press box and starts to exhibit a swagger both in the offensive zone and more specifically in the defensive zone. He's already incredibly good at using his stick to take pucks from opponents and is quick enough to turn that play into a transition for the Sens. He's also off the charts in terms of hockey IQ - I've heard people compare his hockey IQ to Alfredsson's already, which I personally find hard to believe, but that shows how incredible the talent is within this kid.
His point totals aren't exactly screaming elite offensive D-man, but believe me, this kid has it and more. His passes are crisp and confident, usually flipping up the neutral zone to hit a player in full stride. He also has the knack of the 'slap pass' which is hard for vets to achieve, let alone wet-behind-the-ear rookies.
Lastly, his shot is a cannon, he just doesn't use it enough...yet. He will and when he does, combined with the weight that he'll inevitably gain, he'll be a force in the Eastern Conference for the next decade plus.
People with comments such as 'no he won't' in response to will he be as good as Rafalski simple haven't watched him recently. And that's fine, probably shouldn't be commenting, but he's right in that area of talent + desire.
