Jerry Jones plans on remaining general manager of the Dallas Cowboys for the next 15-20 years.

"The facts are that I really do think the way things have rolled out that I'm getting to do some of the best work that I've done, relatively speaking in my career of these last several years," Jones said.

Jones turned 71 in October.

"Of course, I said it, and I really meant that and just think about that a minute: Why wouldn't you?" Jones said. "One of the reasons that I to some degree have taken the risks that I have over the years and kind of had the professional life that I followed is so that I get to decide when enough is enough. So I do get to decide that. It's a certain part of working for yourself if you still are standing when the time comes. So I get to really make that decision, and I want to make it in a way that I think is in the best interest of the team, franchise and really our fans.

"A lot of people just need to hear me say I know it's in our best interest for us to operate the way we have. It's unfortunate that over these last five or six years that we haven't had a few things turn right for us at the end of the season, needing to win one of out of two games to get into the playoffs, having a healthy quarterback, all of those things. But we've been a lot closer than it seems."

Al Davis remained de facto general manager of the Oakland Raiders until he passed away in 2011 at the age of 82.
