I think it's 24 to win by for England

how much will England have to win by? maths isn't my strong point!

After Wales' huge victory in Italy they now sit top of the table. Ireland require a 21 point win in Scotland to take top spot

With Dunbar out and Fife and Laidlaw in, I wouldn't call that full strength.

Cmon Scotland

Hello and welcome to Ultimate Rugby's coverage of the last weekend of the 2015 6 Nations. This match-up sees title contenders Ireland travel to Murrayfield to take on bottom placed Scotland. Both sides will look to bounce back from poor performances last weekend against Wales and England respectively.
Ireland go in this afternoon knowing that a win will leave them in a very strong position to secure a second successive title.
This years Championship will most likely come down to points difference if Ireland, Wales and England all win today. A win for Ireland by 5 more points than England will bag them the much coveted Championship and will leave them in a great position heading into the World Cup.
With that in mind Joe Schmidt has resisted the temptation to ring the changes and has only brought in two new faces in Fitzgerald and Healy.
Vern Cotter will be keen to avoid the wooden spoon in his first year in charge and as has selected a full strength team including young Adam Ashe and Jonny Gray.
Stay tune for kick off coming up at 14.30

Gotta back the green c'mon Ireland
