If, deep down, you truly believe they are going to win why wouldn't you put money on it? I believe they can win. I'll be rooting like hell for them to win. Here's the thing, I do have easy access to betting being in Canada and I'm not touching this one even with the Dolphins getting +1.5 Therefore when I say I don't think they'll win I'm just being honest, which is what you seem to have a problem with.
If you prefer though I can lie with the best of them: THE DOLPHINS WILL WIN TOMORROW, I TRULY BELIEVE THAT AS ALL REAL FANS SHOULD!!
