ENGLEWOOD, Colo. (AP) - Peyton Manning writes down his New Year's resolutions on index cards.

Though he refused to divulge what's on those cards, he never left much doubt about what his day-to-day goals on the football field were for 2012, the year of his comeback.

Work hard. Improve. Keep building chemistry.

Those are the only ways to get to the ultimate goal - winning the Super Bowl, which is something Manning and the Denver Broncos are now favored to do.

Yet to hear Manning tell it, even if the Broncos do win it all, there will still be room for improvement - quite a tall task for a quarterback who compiled some of the best numbers of his career and a team that finished tied for the league's best record at 13-3.
