Do you think a 4 game playoff sample is the same as an 82 game regular season sample, particularly when the topic is regular season? (That sample shows that Nylander is as good a scorer as Matthews, Marner, and Tavares combined.)
Yes, JFresh has a prediction that Nylander would be very good on the rush. I don't disagree with that at all, as it agrees with the eye test. I don't see how his being very good on the rush means he can't be good on the cycle. That stat does not mean 99 % if his chances are off the rush, but that he is in the 99th percentile of effectiveness when he rushes.
I don't disagree with you that the burden of proof lies with him, and I haven't disagreed with either of you on the subject of his plays. All I have done is point out that the particular stats you used aren't particularly relevant.
