I wouldn't compare Scheif's growing pains with Laines- totally different.
Scheif couldn't stay on his feet - he was a lightweight but he was a good skater.
Well, I was watching Scheifele play especially in the two WJC tournaments that he was in at those times, and honestly I have to say that we see it very differently, if you think that he was a good skater already then. He was not at all special with his skating even against his peers. What was very striking about him was that he was in general a quite skinny kid with weak legs specificly.
Sure, he had problems with falling easy, which btw Laine hasnt had too much, but Scheifele was having problems with his skating otherwise too, because of those weak legs. Not too impressive first steps either, and I dare to say that his top speed was in fact weaker than Laine’s when they both were 19 year old’s.
I saw Scheifele play also in several Jets games during those years and after that, as the Jets were one of my favorite NHL teams for sure even before Laine was playing there. For three years I practically was quite sceptical if Scheifele would ever become a true star player. I could see then already very impressive skills and especially it was easy to see that he had very high hockey IQ. But it was just his weak physics that kept me still doubting him. Cool that he has been so driven and training with good methods that strengthened his legs and gave him the much needed power and explosiveness to his legs. And also he has done enormously well with training his stamina.
He has done exactly the training that Laine needs and has been already even doing. But Laine needs still two or three years of the hard physical training to be in relatively similar physical shape that Scheifele is at. Most probably even more time is needed and no bigger injuries should occur during that time. So it is partially also about luck from that part. But at least I can assure that Laine has the similar kind of optimal training attitude that Scheifele has. He wants to do everything possible that is needed for him to make himself a better player. He is extremely highly motivated and willing to work very hard in the exercises that are needed for his development.
I know that some North American fans are not sure how hard Laine is training or how good attitude he has towards training. I can assure you that no need to worry, as he is in the very rare group of extremely highly motivated very talented players that there is. He has exactly the kind of attitude as Crosby, Scheifele and other real top attitude guys.
The same goes with the other Finnish rising star Sebastian Aho, whom is also extremely driven and is on his way to become one of the best players in the whole league. I know that quite a lot of people are even still sleeping on the magnificent skills and potential that Aho has, but in a year or two already he will open even the rest of the closed eyes so far. And I’m sure that in a few years latest the same will happen with Laine and the surprisingly big crowd still doubting him.
