If you listen to sports fans talking about the teams they love and follow, some of them will refer to their team as "we."  For example, "We need a new quarterback" or "We WON!" We Browns fans are guilty of this especially in our misguided attempts to intimidate a Steelers Fan with "We're going to kick you're @$$" on Sunday.  It's a hard habit to break.  After all WE buy the tickets, WE wear the merchandise and WE cheer at the top of our lungs...so why can't WE take credit for the team's success?  Well, if WE were actually a member of the team who put on pads and a jock strap each Sunday and stepped onto the field, then it would be appropriate.  Otherwise a coach of the team can use "we." So can former players. And, probably anyone on the payroll could get away with it. But a fan? Until you take a few snaps or get sacked a few times on the field of play you've got to give the credit to whom it it is due.  I think it might be o-k to say "Our" team is going to beat your team  ....etc. or does that imply ownership?
