England will now chase a Grand Slam in Paris, a title they last won in 2003 when they were in their pomp and headed for their solitary World Cup triumph.
For an hour England were in total command against Wales but then lost their way. Jones wondered whether that lack of finishing bite happened because he had gone to his bench too early.
"We stopped attacking them and tried to protect the lead, but if someone had said five months ago that we would be 25-7 up against Wales after an hour, we would have been very happy," he said. "It is just about making better decisions in the last 20 minutes and it was nothing to do with fitness."
England's upgrade comes with all sorts of intrigue.
Bad boy Dylan Hartley's upgrade to captain, the rejuvenation of Chris Robshaw and Dan Cole, the rise of impressive tyro lock Maro Itoje, the midfield choices after Manu Tuilagi's injury recovery and the thrust on the wing from Anthony Watson.
