Jeremy Guscott: Wales’ vice-like defence fuels Six Nations Grand Slam run

Wales roll on. Just as coach Warren Gatland predicted before the start of the Six Nations, his side have built up some formidable momentum after getting over the hurdle of France away on the opening weekend.
Eighty minutes against an excellent Ireland side now separates them from a 14th successive Test victory and, more importantly, a first Grand Slam since 2012.
Their performance against Scotland showed the qualities that their excellent run has been founded on.
The D in Wales’ DNA
The most distinctive part of Wales’ DNA is their defence. They have only scored nine tries so far in this tournament – the same number as Italy – but have conceded just six, the fewest of any side.
Their fitness, durability and organisation is more of a hallmark than incredible try-scoring.
Former Great Britain rugby league international Shaun Edwards has been in charge of their defence for more than 11 years and that continuity means the defensive system is ingrained.
Their ethos is to meet line speed with line speed. They come up flat and fast, especially close to the breakdown.
Individually, their first-up tackling is very good and, when that fails, their scramble defence is sharp and committed.
In the first half, Scotland wing Darcy Graham pinballed through Josh Navidi.
