You have no way of proving A or B.
Crouse:
6 threads posted on HFboards with "Crouse" in title
4 with ARI trades with Crouse included in them
2 "insider" news threads about Crouse (Flyers interested, Eastern Conf bets on Crouse to TBL)
Now, Coleman was traded in the middle of the 2019-20 season before the league shutdown. So let's take a look at these same metrics during that season.
From Oct 1st:
1 Unrelated Coleman thread, "NJ fire sale" Nov 2019
2 Coleman as an additional piece Dec 2019
3. Coleman to BUF as an additional piece
4. Coleman to the Leafs
5. Coleman/Vatanen
6. Coleman leaving speculation thread
Interestingly enough, while browsing there were at least 4 more threads with Crouse either in the title or the main piece in the first post. They didn't show up in the original search because of their age.
Of course, fan speculation is one thing, but maybe the GM's around the league were more hyped about him. Neither of us can prove one way or the other. But given the results here, safe to say that the fans, at least on this forum, are more interested in Crouse.
Ultimately of course our opinions are subjective, and the only thing we can say for sure is that he's younger than Coleman.
Now after searching through ~60 pages of threads I think it's time for me to go take a dump and a nap.
