Eddie Jones believes that the introduction of relegation and promotion to the Guinness Six Nations should be considered.
On Saturday, England beat Italy 57-14 at Twickenham. It was the Italians' 21st consecutive defeat in the tournament.
"I think they should always consider rewarding merit - it doesn’t matter what competition you’re in," Jones told BBC Radio Five Live's Sportsweek.
The organisers talk about the Six Nations being the best rugby competition in the world and it probably is close to it, but to improve it you’ve got to find a way of making sure you’ve got the six best teams in Europe always playing in it.
If that involves relegation and promotion then it’s something that should be looked at very closely.
Yesterday's victory saw England bounce back from last month's defeat to Wales - one which ended their Grand Slam hopes.
Jones said their reinvigoration was aided by some tough training sessions featuring Georgian players along with the odd night out.
"We had a couple of hard training runs against Georgia, a few nights on the beer. Just relaxing, enjoying each other’s company and a bit of fun organised by the players in between the hard training. It’s just finding that right balance.
"We went punting in Oxford last week. We did a tour of some of the university buildings - I don’t know how much the players enjoyed that part! It was a good education for them and a bit of fun."
