Romo has shown control of his offense as he has allowed running back DeMarco Murray to carry the burden, which has reduced the amount of turnovers on the offensive side of the ball.
"I don't know that I can say that I've ever seen him play better," Jones told KRLD-FM. "We've seen him certainly do what Romo does. That is instinctively make plays.
"We've seen him basically protect the ball, and I know for a fact that he's bought into his working and the coordination that he has to have with [play-caller Scott] Linehan."
Romo has thrown for 1,510 yards and 11 touchdowns to five interceptions.
