Don’t really get this from a Seahawks POV, why would they want this circus to come to town? They’ve got one of the best WR tandems in Metcalf and Lockett (one of whom is turning into a superstar this year), a bunch of useful WR role players, plus proven chemistry and a winning formula. Brown is a known agitator and distraction even if you ignore all his legal stuff, just ask the Raiders. I think the chances of him completely sinking the season are much higher than the chances that he makes them Superbowl favourites.
And yeah, they’re currently fun for neutrals to root for, this would reduce that considerably.
