The Cowboys owner explained Tuesday that there's no need to hire a GM who would just answer to Jones anyway.
"It's often said, Why don't I get someone to be the GM? Why don't I get someone to pick the players?" Jones said on 105.3 The Fan on Dallas. "Well, who in the world do you think that person, when they walk through the door and say, 'We want to get this player, and we want to pay this player,' what in the world do you think I'm going to do?
"I'm going to sit down, and I'm going to go through it, and I'm going to say, 'Show me the player before I write the check. Show me the player. And let me see everything about the player.' Well, rather than have that happen, I get involved in it and get to know everything there is to know about the players before they get through the door."
After a blowing a 23-point halftime lead on Sunday in a 37-36 loss at home to the Green Bay Packers, the Cowboys fell to 7-7 but remain in the NFC East race. Going into a game this weekend against the Washington Redskins, Dallas trails the Philadelphia Eagles by one game in the division.
Jones acknowledged this week that the Cowboys have some personnel issues stemming from injuries and offseason moves. But he went to bat for quarterback Tony Romo, who threw two costly second-half interceptions against the Packers. One came with 2:46 left in the game after Romo changed the play call from a run to a pass.
Jones is fine with Romo taking chances on the field.
"When it basically has to unfold for him out there, the defense gets out of their structure, we get out of our structure on pass routes," Jones said. "All of a sudden, you're into a little more sandlot-type football. In doing so, there's more risk that's involved. Make no mistake about it: With where we are with our personnel, we're going to have to take risks."
