4. Antonio Smith, 34
Unlike many of the players in this list, Smith has been to the Super Bowl before. As a member of the Arizona Cardinals in 2008, Smith was on the receiving end of one of the most gut-wrenching finishes in Super Bowl history when Santonio Holmes came down with the go-ahead score in XLIII.
That proved to be Smith’s final game with the team that drafted him out of Oklahoma State in the fifth round of the 2004 NFL Draft, as Smith went to play five seasons with the Houston Texans before a one-year stint with the Oakland Raiders in 2014.
Amazingly, Smith has missed just one regular season game since the 2006 season. He suited up in all of the Broncos games this season, recording 2.5 sacks, Smith’s lowest sack total since 2006. With that in mind, this could very well be Smith’s last go at it. Here’s what he told the Broncos’ team blog last week:
"I’m excited to enjoy this moment. It ain’t really like I’m doing much to ride off into the sunset now. It’s like, ‘I’ve got the opportunity of a lifetime. I’ve got the season. I’m in the moment."
Smith is the first of two 34-year-old defensive linemen on this list…
