All we have to go by is the article in the Athletic referenced earlier. My reading is that there was a lot of unfavorable, unkind discussion of Laine in the Islander dressingroom spearheaded by a teammate who had first hand info from someone on the Jets team.
Your adding some of your own content/spin there if your quoting the Athletic.
I quote: Islanders who know
players in Winnipeg talked about Laine a lot in the locker room and not much of it was kind.
Notice in the quote, it says players with a plural, plus says Islanders with a plural......meaning multi players, not a single player but multi players. So if true, multi team mates of Laine had unkind comments regarding him.......which isn't good look for Laine. If it was one guy, well some times two guys don't see eye to eye but doesn't mean either are bad guys. But when more and more of your team mates are saying unkind things.....well that looks much worse on Laine.
Again this is rumour only, not confirmed so I'm not placing too much stock in it at this point.
