I'm not sure how you can evaluate that at all. There is no way, for anyone outside of himself, his friends or his family, to know if he has the personnality for it or not.
I’m sorry but some people have very good intuition and people reading skills. I have seen improvements in his body language since being drafted and signed that would indicate he is growing to the AHL level. But after that I’m just not sure he has the IT factor to play very physical games in the NHL. Crouton ( Drouin ) for example only got to the NHL based on skill, which he has much more of than kidney. Also, droning ( drouin ) shows classic signs of wanting to play hockey but not at all wanting to sustain a physical effort to play in the bigs. His body doesn’t like it, he hates the refs, he hates when someone hooks him and doesn’t get called. To make the NHL you have to have the mentality of f*** it I’ll do whatever it takes even get pounded into the birds night after night. Your body shows signs of your mentality and right now even though kidney is improving he will have to step up his Beast inside in order to translate his skills on a nightly basis.
Salfkovsky, for example, showed he was willing to do whatever it took to play in the NHL take hits etc etc, but his mind started to weaken over time from getting crushed, his confidence lowering. He started to show classic signs of this is to hard and I don’t know what to do next which is why in my opinion they shut him down for the season.
