Well, if anyone wanted my advice on all of this, I would give the same advice to the players and the fans. I would tell the players to ignore the idiots who incessantly attack them and see a game as a matter of life and death. Don't respond and certainly don't get into a back and forth with them and lower yourself to their level.
And to fans, I would say the negative comments are not what being a fan is about. Yes, we get upset because we have passion for a sport we've followed all our lives, but that doesn't mean we should speak every thought that comes into our heads or belittle and attack the players on the team. Constructive criticism is fine, in my view, but the destructive kind I see at times is useless. And I would also add that attacking players on social media is over the line.
Now, since many would not listen to me from either group, what is the solution? All we can do is our own part.
