Lane Hutson isn't BAD at defending, at least not at the college level. I think the real question is if his style of defending can properly translate to the NHL. He uses an active stick and sound positioning, along with using his strong ability to read the play in order to disrupt attacks. He will get beaten physically and in many one-on-one battles even in college - so my question is if those tools are enough in the NHL, when the size and speed is so much greater. I suspect next season he will work to improve his defensive game in college, as there's not much left to prove offensively for him.
I am confident with what I've seen that he would be able to transfer many of his offensive skills to the NHL, but defensively remains a big question, and his stature plays a much bigger role than a lot of people realize. I also think it is possible that his elite offensive skills are able to propel him to such highs where his deficiencies are minimized. I think he is still not a top 10 pick in a re-draft, but he is trending in that direction.
