Check out what David told The Associated Press today.
"I've heard that (fans thought he was key to helping the team get to the Super Bowl) a little bit, just being the missing link, and of course, with me going to the Super Bowl the year before, everybody's looking at it as: 'This guy was a star on a Super Bowl team, he must be a great player.'
"No doubt I'm a great player, but at the same time, I'm going to just come here to do what I can to help the team succeed, whether it's special teams, whether it's starting cornerback.''
Confidence is great, but let someone else tell everyone how great you are. A little humility will go a long way.
