It's my team playing on the biggest stage, of course I'm going to be nervous. If it weren't Seattle, we'd all be fretting about playing Rodgers and that Packers O. Hell if the Cowboys were here, we'd be worrying about stopping Murray and generating pressure on that O-line. If the Lions were here, we'd be worried about that D-line and stopping CJ and Tate.
This game is going to be the toughest we've played all season, and I'm not gonna be surprised if we lose. But I've spent this entire season fearing opponents, and at this point, I'm kinda tired doing it. We're underdogs? Then the worst that happens is that the expected outcome (IE: Seattle wins). Oh sure, we could get blown out, but I highly doubt that it's gonna happen.
