Quarterback Jay Fiedler, who will play the entire first half, needs to rebound after a horrendous performance in the 24-7 loss to New Orleans.
Ricky Williams, who also will play a half, needs to get a rhythm going and put up some yardage.
The special teams units need to have a good night after allowing a touchdown against both Tampa Bay and New Orleans.
The run defense needs to be better.
Put simply, the Dolphins need to give themselves something to feel good about — all the way across the board.
"It's the third game, that's what makes it important," said Coach Dave Wannstedt. "We need to go out and play good. We need to go out and make some improvement and clean up some of the mistakes we've made."
A big difference in this game also will be the fact the Dolphins actually prepared a game plan for Saturday night's game, something they didn't do against either the Bucs or Saints.
"We've been fairly sloppy the first couple of games, but we played two games in four days," said cornerback Patrick Surtain. "I'm not making excuses, but we didn't have our legs. We've been working this week and we (did some) game-planning, so we'll be much more prepared for this game, and hopefully we can go out there and take care of business."
