JJ is a Viking

[OrangeInKy]

I don't pay a lot of attention to the SF football scoop, but what has JJ done to make him "unpopular"? I haven't read or heard anyone complain about his attitude, etc. Could you elaborate? Enquiring minds and all.

It’s more about what he does and says to opposing players. Google it, players around the league hate him. His teammates may have liked him, IDK.
Here is one example, but not the only one.
