George Ford rescued England with an 83rd-minute try to secure a 38-all draw with Scotland on Saturday after the Scots had come from 31-0 down to lead 38-31 in one of the most remarkable games in Six Nations history.
Jones is keen to use the experience of Nowell and Ben Te'o against Scotland, with England still in with a chance of snatching the title out of Wales' hands.
'They never understand, ' said Jones.
"We have had a good preparation and the side is going to be in a great state to play against Scotland on Saturday".
There were four changes in all for England, with Jack Nowell replacing Cokanasiga on the right wing and Henry Slade coming in for Ben Te'o as the center partner for Manu Tuilagi.
The countdown is on... "We don't need to rush him, we'll bring him through carefully and he's got a long career ahead of him". 'We've got a good plan in place for him, ' said the head coach. I don't need to reveal my selection plans for the future, but I do know that we'll have him ready for the World Cup.
"The thing I enjoy most about playing with him is how much he loves it, how much he loves being around this place and being out there on the field", added Farrell. "As soon as you tell them they're not in the team, you get this blank look". He'll feature very strongly in our plans for the future but we just feel this week Jack is our best player in that position, ' Jones said.
Despite scoring a double against Italy, Brad Shields has been assigned the role of a finisher with Mark Wilson starting at blindside flanker while Ben Moon replaces Ellis Genge at loosehead prop with the latter joining the reserves.
"If we impose our game on Scotland it'll be pretty tough for them", said Jones, whose team finished fifth last season after losing their last three games and then lost two in a row against South Africa.
Saturday's game will also see Leicester Tigers' Ben Youngs reach a milestone as he is set to become the most-capped scrum-half for England with his 85th Test appearance. If they are to be crowned champions, England must win and hope that Ireland beat Wales earlier in the day.
