I get it with 3 websites that it must be tough and I have no issues with fans of other teams writing these articles. However, there needs to be some research and integration into the team you are writing about so that you have some idea what you are talking about.
Also, giving the platform to just anyone is going to cause frustrations. One of your most frequent writers is a Brewers fan, but is known for his bizarre takes like moving Braun to SS and 3B, even up until he was ready to retire. While long tenured members may shrug it off, new visitors to the website are going to think the membership is mostly idiots.
