Feeling good: Well, lots of reasons to feel good. The Dolphins have yet to win a game this season, and a lot of people think they might be trying to lose on purpose so they can get the No. 1 pick in the draft. I don't buy that the players are trying to lose, but they have played very poorly and are already on their backup quarterback in Matt Moore. Even their potential strengths don't match up well with the Giants. If rookie running back Daniel Thomas were healthy, they could maybe get a run game going against a Giants defense that doesn't stop the run well, but Thomas' hamstring will keep him out of this game. Top receiver Brandon Marshall is a mismatch for most cornerbacks, but the Giants' Corey Webster and Aaron Ross have the size and the speed to cover him. Basically, it's hard to see too many ways that the Dolphins might be able to win the game.
Cause for concern: I guess a winless team can be a desperate team, and the Dolphins really do have nothing to lose. They have the kinds of players, in Marshall and Reggie Bush, who can beat you with a big play, and if they hit a couple of those they could theoretically put the Giants on their heels and control the game. The Giants showed a few weeks back in a home loss to the Seahawks that they're not immune to a "trap" game in which they play down to their opponent. I don't see it happening here, but anything is possible.
