A good halfback is key in defusing pressure when it's applied IMO. Its not enough to be able to take advantage of forward dominance as this will never be the case for the entirety of a match.
Gordon did this very well at the start of the year with some really pinpoint clearing box kicks against Wales. Since then he has progressively worsened with Ireland being his nadir.
I think all our 9s have looked worse with the accelerated timeframe for clearing the ball; where they had ages to fuck around behind the caterpillar, now they don't. Tate has probably been impacted the most.
I can't really see why Gordon's box-kicking went from the level of the Wales Test (very good distance and accuracy wise) to what we saw last weekend, although the increased pressure on the breakdown from Ireland (urgency and egregious lolly-gagging where they shouldn't) was probably a big factor. Kudos to Ireland.
As stated by someone earlier, better quality ball more on the front foot works wonders.
Longer term I think McDermott has the most upside of those in the squad now (if they can tidy up his passing options and delivery) ; others outside it will have chances...
