He sees him in practice and realizes young quarterbacks will make mistakes. What he didn't anticipate was that his entire team would melt down against the Saints last week. Now, Parcells has to regroup and regroup quickly. This Saturday night game is crucial for the Cowboys. If they win, they are in good shape because they finish with home games against the Eagles and Lions. The Cowboys get a huge break in this game because the Falcons might be down to their third-string running back. Warrick Dunn is a long shot to play, and Jerious Norwood is all but a scratch. That forces the Falcons to use fullback Justin Griffith as the halfback. Of course, the Falcons' best runner is quarterback Michael Vick, and he will no doubt look to run against the Cowboys' 3-4 defense. For the Falcons, this is a must-win game. At 7-6, the Falcons can't lose a home game if they want to stay in the NFC wild-card race. Falcons coach Jim Mora needs a great game from the defense. He needs to harass Romo into mistakes, and he has to make sure potential interceptions in the hands of defensive backs aren't dropped. If the Falcons are going to have a chance against the Cowboys, Vick has to carry this team more than ever before.
