@The Ghost Brown is a real piece of work. Last year he was sued over injuries to a toddler when he threw some kind of furniture from a balcony. One of the local news channels in Pittsburgh just had a report on several civil suits pending against Brown. Most of these allege that Brown stiffed certain individuals and businesses. Owed money, but never paid. I'm trying to find a link to the report, but I guess it hasn't been posted yet.
Steelers fans were unhappy when Brown left. But I think the Steelers, Raiders and now Patriots are happy to be rid of him. It's not just these current allegations of impropriety. Brown is just an all-around jerk. I don't care how talented he may be. He's just not worth the aggravation.
And I suspect other NFL teams are going to be wary of Brown too -- for all the reasons stated above.
