Personally the instances I've used "we" when describing a sports team are when I'm on that sports team, or on the staff of a sports team. The way I've justified that thinking is do the Twins know I'm a fan of their team? Do they care about my opinion of the team? Probably not, otherwise D Santana would be released already It's not wrong if fans want to use "we" to feel like they're a part of the team. I may roll my eyes when I read it or hear it, but it's not something to get upset about. My views align more with Craig and Ben where I just don't identify myself that way with sports teams.
