Nobody says “of course we’re going to win” because there is no guarantee.
To use another cliche: “On any given day, any given team can win any given game.”
If you said, “Of course we’re going to beat the Fightin’ Pacifists. They’re 0-32 over their last two seasons. They SUCK,” well, the first thing that would happen is that your newspaper article is on the Pacifists’ bulletin board, and every member of that team is out to prove you wrong. Moreover, it is possible and almost certain that one or more members of the Pacifists will be out to do you physical harm, and will likely get away with it.
If you win, big deal. You are an ass for predicting victory over a bunch of cupcakes, and the sportswriters (who, remember, vote for- and influence others’ votes for- MVP awards and other recognition, bonus clauses for winning which are almost certainly in your contract) think that you are an airhead or an asshole or whatever, and their influence carries. Oh, and if you’re a hockey player, forget the Lady Byng.
If you lose… oh, you poor bastard. You’re the guy who fired up the lowly Fightin’ Pacifists and caused them to beat you. Your coaches had already probably marked that game in the win column. Now you’ve hurt your chances at the playoffs (especially in football, where the season is so limited). You think you’re not gonna pay for that in practice? Oh, yes you are, and so is your entire unit. You’re gonna get crucified in the papers, home of the aforementioned (important) sportswriters. Coach is gonna fine you. The locker-room “kangaroo court” is gonna fine the shit out of you. Ownership is going to take a long, hard look at the “locker-room disruption (hint: that’s you).”
You know what might happen then? You might get traded. To the Pacifists. Now you’ve got to show up every day to a locker room full of people you just got through calling losers. Now you, too, are a loser. Have a fun rest of the season, loser.
Always, always, ALWAYS make sure in pregame interviews to express respect for the competition. And the 0-32 Fightin’ Pacifists are a “dangerous opponent” because “they’re better than their record,” because “they’ve got a lot to prove,” because “they were in a lot of games they lost,” because “four plays go differently and they’re 4-2 this year,” because “no disrespect to the Pacifists, but nobody wants to be the team that ends that streak,” because “they’re one big play away from blowing a game wide open,” because the Pacifist’s star player is “an explosive talent who can change a game all by himself,” or any of a hundred thousand other cliches. But mainly because you have nothing to gain and everything to lose by running your big fat mouth.
And as to the “illiterate boob” comment, I can produce thirty pages on the fundamentals of a caucus electoral system in less time than I can produce thirty pages on why the new goaltending rules are ruining hockey. But I’d rather write the latter than the former.
