The European Nations Cup, or ENC – sometimes referred to as the Six Nations B – is the European Championship for tier 2 and tier 3 rugby union nations.
To develop the Northern Hemisphere rugby scene, I read somewhere that the top ENC team should have a promotion/relegation playoff with the worst 6 Nations team. If a country from the ENC, eg Romania is good enough, they will then play in the 6 Nations.
