Cowboys head coach Jason Garrett and offensive coordinator Scott Linehan are likely the two men on the hot seat following Dallas' disappointing start to the season.
"I think that after eight games, when you've won three, that's cause for concern," Jones said, according to NFL.com's Jeremy Bergman. "Our record could be better than it is right now and we'd still be in trouble, we have to play better.
"Each player, front office person, coach -- and me -- is going to have to do better."
The Cowboys entered Week 9 tied for 25th in points per game (20). Despite the trade for wide receiver Amari Cooper, who scored a touchdown in his Dallas debut against the Titans, the offense still looked lackluster, as it has all season.
