"Michael Vick is first to admit that he hasn't fulfilled expectations this season.

He signed a blockbuster contract extension in August that made him one of the NFL's highest-paid quarterbacks, but he isn't among the league's top passers this year, hasn't stayed healthy enough to play in every game and probably won't make a return trip to the Pro Bowl.

But the Eagles have four games left to right their wrongs, and Vick plans to make each one count.

These final four games aren't just a test of his leadership, he explained after Friday's practice, they're a test of his ability to tackle adversity and criticism only one year after nearly everything fell into place for him.

"This is different," Vick admitted. "This is the first time going through a situation like this. You go through different things in your life — different stages, different phases, whether it's in football or off the field. You've got to be able to adapt and deal with it."
