its a fair point, despite knowing how to dig deep and front up when it counts, and having one of the best packs on the planet, England definitely need to work on unleashing their backs and playing with more fluidity when required. I have no problems England beating France or Australia by any means neccessary, but against a team like the USA, who are much improved, England really should have stuck at least 50 on them, if not a good bit more.
But I don't think they are papering over the cracks, you need a few years to create a good solid basis for a world cup team, Ashton hasn't had long and I think he has an excellent attitude, his coaching credentials are certainly up to standard. I just think to judge him fairly, they need to give him another 18 months in the job and look at bringing in a 3rd person like Martin Johnson to make sure Ashton has time to do what he does best. Keep Andrew as Director of Rugby, make Ashton the national coach and make Johnson the national manager. With this set up, I think England has enough talent in the premiership to get back to the top of the rankings.
In all, I think its a little early to talk about papering over the cracks, as he won't have a chance to fill those cracks in at the foundation until after the world cup, when he can come up with, along with others, structures to make sure Team England gets what is required to help them back to the top.
I don't think even the most fervant England supporter is stupid enough to think "England is back" in terms of sustained results and long term ranking, we are simply showing our teeth, digging in and making a bloody good fist of things, considering the poor cards we've had to play with. To get back where they were, England need at least 2 years of good results to come even close, that's after the world cup has ended.
