It's a rest week in the Six Nations, so I've got a challenge for you: how could a team win the championship despite losing four of their five games? Assume no tied matches
(For those who aren't aficionados, you get four points for a win and zero for a loss, plus potential bonus points: any team can get a bonus point for scoring four tries, and a losing team can get a bonus point for losing narrowly.)
Please spoiler answers đŸ™‚ I'm interested if my way is effectively the only way.
