"It's football," David said. "The more you play this game the more things you understand. You are not going to always have the best season or the best game you want. So it's all about bouncing back and how you come back from situations like that.

"Each player out here feels like they have something to prove, everybody from the second-team kicker to the long snapper. Everybody wants to do their job as best as they can and prove to people that they are a good player."

"Unless you are Will Smith or Charles Grant or Drew Brees you really don't have too much (job) security," he said. "In any position in the NFL and at any training camp it's going to be competition. Last year I really didn't have any security. I actually battled for my job. And it's the same thing this year. Ever since I've been in the NFL I've had to compete for my position, and that's something I'm used to. It's normal. It's nothing new to me. I just have to keep playing football."
