When you are brainstorming about possible mascots or icons for your athletic team, you should bear in mind that at some point, probably quite soon, whatever you decide on will be bandied about versus whatever some other team has decided on. And, because it's sports, you will want to sound all bad-ass and threatening. That's why--although they are widely popular things and would probably make for great fan appreciation days--nobody chooses The Puppies or The Cupcakes. And yet today, when I was half listening to a litany of imminent matchups on NPR news, I heard "The Sharks take on the Maple Leaves."
It's true that if unexpectedly covered by a flurry of maple leaves, sharks would probably be baffled and thus bested, but one wonders if that is the kind of battle that hockey fans are really looking for? I'm looking at you, Canada.
