The obvious choice is Michael Vick.
The quarterback is always the most important position on any team. We'll start with him and then I'll give you five other players that are critical to this season's championship run.
Michael Vick is entering training camp and the 2011 season as the unquestioned leader of the offense. He played so well in relief of Kevin Kolb last year that there was no way Andy Reid could keep him out of the line up.
In the seven games in which he started and finished during the middle of the season, he averaged 288.4 yards passing per game and had an average QB rating of 107.4. Those are excellent stats.
However, in his last four starts (including the playoff game) he averaged 266.7 yards passing per game and had an average QB rating of 85.4. The average yards passing drop off isn't as concerning as the QB rating.
QB ratings take several things into consideration but most notably are completion percentage and INTs. In the seven games I calculated, Vick only threw two INTs. In the last four, he threw five INTs.
There were some folks who, by the end of last season, wondered if defenses began to "figure him out" and learned how to effectively defend against Vick. There is certainly some logic to that as you can see by his numbers decreasing toward the end.
Ultimately, Vick needs to step up his game when it comes to crunch time in the playoffs. He has to prove that he can win when it matters the most. His career playoff record is 2-3, at the end of this season let's hope that record is 5-3.
This team will go as far as Vick can lead them. He is the most important piece to the puzzle by far. But who else will need to turn in an outstanding performance this season?
The right answer would be "everyone"! But here are my top five important players that aren't named Michael Vick.
