They way fans were looking at Struble as a prospect was the total opposite to the way they look now at Lane Hutson. Struble was not flashy in the NCAA, modest stats, but we knew he was an elite athlete, very strong physically despite the fact that he was injury prone with a groin problem that seems to be solved now. But Struble had a package and a style of play that was relatively easy to project into the NHL. He was a heavy duty machine that you knew would be able to do the basic job a D needs to do, which is to defend. Any upgrade on that would come with experience.
Hutson is the opposite, he is like a fragile high tech machine. Very good to do high level tasks on offense, but will he ever be able to defend at a decent level in the NHL and resist physical play? Fans like the spectacular stuff with prospects, and big stats, but forget to think about how it is transferable to the NHL. That's why Struble was undervalued as a prospect, and Hutson is way overvalued now. To meet expectations placed on him by many (1st pairing D) he will need to overcome so much. If he succeeds at that he will really be one of a kind.
