Kevin Kolb has proved himself as a viable NFL starter in the absence of Donovan McNabb after waiting two seasons to get his opportunity. ?The biggest thing to do is take it week by week and just stay focused," said Kolb. "If you are trying to look at the whole picture you get into trouble doing that kind of thing. Again, like I said before when all of this started, I am just going to play for the here and now and keep working like I have been. The opportunity will come when I get my shot again and when it does hopefully I can ride it out as a starter from then on.?
