There's no doubt that Denver Broncos quarterback Peyton Manning is one of the best players in NFL history. He's got the numbers and records, he's got the MVP trophies, and he's got a Super Bowl ring to prove it. But he's also 39 years old and saw his play take a turn for the worst over the last five weeks the 2014 season following a nagging leg injury.

During that span (including playoffs), Manning averaged only 240 passing yards per game while throwing four touchdowns against six interceptions. As a result, many thought the five-time MVP was done. However, Manning is back with the Broncos this year and even looking toward 2016 and beyond.

"I am really enjoying myself...I feel good and feel I can help and contribute," Manning said on ESPN when asked if he wanted to play next season.

If you look at Manning's overall numbers from 2014, the veteran produced another stellar season, throwing for 4,272 yards with 39 touchdown passes against 15 interceptions. However, Denver left a bad taste in fans mouths with their divisional playoff loss to the Indianapolis Colts. Manning managed just 211 yards on 46 pass attempts in that one.

With the emergence of running back C.J. Anderson and the recent signing of free agent guard Evan Mathis, new head coach Gary Kubiak will likely place more of an emphasis on the ground game than previous head coach John Fox. That should help alleviate pressure from Manning and keep him fresh for the post-season, should the Broncos claim a spot for the fifth consecutive season. Helping matters will be Denver's top tier defense.

The Broncos finished 2014 ranked third in yards allowed per game (305.2), second in rush defense (79.8 yards), ninth in pass defense (225.4) and ninth in sacks (41.0). That's not a bad safety net to fall back on if Father Time finally catches up to Manning.

The Broncos will open the regular season against the Baltimore Ravens on Sunday, September 13.
