Fortunately, Foles is about as cool a character as you can find.

“You know you can make it as big as you want it, or you can make it small,” Foles said. “I choose to make it smaller so I can hone in on what I got to focus in on today, so by gametime I know I did everything I could to prepare for that moment. Then I can just go out there and play.”

With last year’s Super Bowl MVP leading the Birds yet again, fans have renewed confidence in a team that looked lost just a month ago.

“I think we’re going to go in there and we’re going to win, I like Nick. I’m confident,” Eagles fan James Brennan said.

But winning all of their games on the road against teams with better regular season records is still a tall order.

“I don’t know about the underdog thing,” Bob Moritz said. “I think right now they’re just playing well. Foles seems to have revitalized the team.”

“We know that’s the situation again, but at the end of the day, I’m not going to worry about that because I’m going to worry about what’s going on in this building and preparing for this game,” Foles said.
