*Disclaimer: I'm only interested in discussing Morgan Rielly as a prospect, his development and his accomplishments. I am not bashing him or Leaf fans*
That's my point of view as well. If Rielly was placed above a guy like Yakupov, Huberdeau, Hamilton and Strome, he either has 1) an absolutely staggering amount of potential, 2) has performed very well over the past year or 3) a combination of the first two. This is based on Craig Button's posted criteria.
In this regard, he has certain things working against him including his injury, which means he missed many, many games. If Rielly is placed above all the aforementioned players, it must mean that he has performed very, very well this season except Strome is producing at an insane 2ppg pace and Yakupov is at a ppg in the KHL, which is great for a rookie (better than Kuznetsov and Tarasenko). Also, Rielly is on a weaker team, which leads to less points and less favourable stats. Does that mean Button thinks Rielly has played and performed so well with respect to the Warriors, that his play over the past few months places him higher than Yakupov and Strome?
If not, then it means that his potential is extraordinary such that it hands down exceeds that of Strome, Hamilton, Yakupov, and, yes, Galchenyuk. How rare would that be? I think that would be on the level of Crosby. I, personally, do not think that that is the case, and I don't know what such an argument could be based off of.
