You missed my update? Well I missed the games too (this year is not that great for my 6 Nations viewing time but it doesn't matter) but I will see the last games tomorrow.
Wales - Scotland: 18-11
Wales won thanks to a good first half (15-6) and to its capacity to hold in the second half time (it seems Scotland was not as realistic as they should/could have been).
England - Italy: 57-14
The difference was too high between the two teams (England had the offensive bonus (4 tries scored) in just 30 minutes) but it seems Italy showed some offensive efficiency in its two tries.
Ireland - France: 26-14
In spite of the score, France didn't show anything and scored two tries in the last minutes but Ireland gave the impression they could score when they wanted and after 60 minutes, the key offensive people were already put to rest while the team seemed to slow down in the second half.
Three teams can still win but for me, it will be either Wales (if they win against Ireland) or England (as even if Ireland wins its game, Scotland would have to win in England for them to become champions).
