ENGLAND ARE VERY POWERFUL AND CONFIDENT
England's win over Wales was a very tight game of fine margins, and it was the visitors' perfect execution of the chance they were given to win the match that proved to be the difference.
When Jonathan Davies kicked into the backfield in the last four minutes at the Principality Stadium, England were able to impose themselves enough to create an opportunity and were then clear-headed enough to take it.
This is a very powerful, confident, internally competitive 23-man England squad.
Individually Joe Launchbury and Courtney Lawes were mammoth in the second row, expending huge amounts of energy. Nathan Hughes racked up some huge numbers, with the most metres gained (75), carries (22) and defenders beaten (three) of any England player.

WALES A REAL THREAT TO TOP FOUR
Wales could have easily won this year's match and when they play with that amount of energy they are a real threat to the top four in world rugby.
Some people questioned coach Rob Howley's decision to withdraw number eight Ross Moriarty after 52 minutes. The Gloucester man had had a blast up until then, a real physical presence with some immense hits in defence.
But it may have been that that impact was a result of him emptying the tanks in the time he was on the pitch, knowing he was going to be taken off soon after half-time. It is not a given that had he stayed on he would have been able to maintain that pace.
The balance of the Wales back row was good with Moriarty everywhere, blind-side flanker Sam Warburton doing the heavy-duty carrying and tackling and open-side Justin Tipuric fetching, disrupting and supporting in space.
They were more mobile than their England counterparts and were a big part of Wales securing seven turnovers to England's three.

SCOTLAND WERE NOT INVENTIVE ENOUGH
Considering they were outgunned in terms of bulk by an enormous France side, the challenge for Scotland was to manoeuvre their opponents around the pitch enough that they tired them out.
With eight pairs of fresh legs on the bench at French coach Guy Noves' disposal, that was always going to be difficult.
Scotland were capable of doing so, the problem was they could not muster the intensity for long enough periods.
It was not physical intensity they lacked. Instead, they had to be dynamic and inventive, and constantly remould their attacking shape to keep France guessing.
France knew that was going to be Vern Cotter's gameplan and the hosts were motivated enough to deny them space and momentum.
Stuart Hogg and Tim Swinson's tries were well worked, but there were not enough moments where they got around the outside or in behind France.
