Dallas Cowboys owner and general manager Jerry Jones has hinted that he could make changes to the team's roster during the off-season.

The Cowboys are roughly $20m (£12m) over the projected salary cap, forcing Jones to decide whether to restructure the contracts of a number of players, offer pay-cuts or even release some of his roster.

However, the 71-year-old - who celebrates 25 years in charge of the Cowboys today - insists that any changes would be carefully thought through before taking place.

"The easiest thing in the world is to change and go look for something new. Something being maybe a style, a player, that type of thing," Jones told reporters.

"That's easy to make that decision. Now you have to know, you're sitting there saying, 'OK, where do I go from here and what type of player am I going to have out there, and how is the best way to use it if there is an asset somewhere else?' You've got to roll the clock forward."

The Cowboys missed out on the playoffs for a fourth consecutive season last year, finishing with an 8-8 record.
