From the things I've heard and seen, Laine doesn't strike me as a lazy worker. He has always had the desire to become the best player out there and it just doesn't fit Laine's personality to train lazily and throw all the potential down the drain, especially now when he has picked his game up from last years into whole new level.
Also, I remember him saying something like this after WJC: "I need to train, train and train to become even better. Without forgetting to rest and eat well". Basically all the things you wanna hear from him at his age.
And lastly, Laine said he isn't one of the those youngsters who likes to party or celebrate big time when something happens. For example, Laine celebrates his 18th birthday tomorrow by playing in finals and will probably just have coffee and cake with his family. So not getting wasted as F like rest of us would do.
If Edmonton drafts him he better get used to driving Ford F Series trucks!
