The heart of the blame lies with the RFU.
Since 2003 England have won one solitary 6N when everyone played **** and we limped over the line. No Grand Slam in 12 years and almost nothing to shout about in that time. Over the same period both Wales and France have won four 6N (Wales 3 Grand Slams and France 2), Ireland have won three 6N and one Grand Slam. Realistically I think England's current pool of players is as good as any of those nations, perhaps weaker in some areas and stronger in others. The players are there, look at the JWC successes. We produce many, many fine players. I'm sure some will disagree but I think that is not the issue.
So what's the common thread? Poor coaching. All the England coaches since the 2003 WC have been, frankly, ****. Nothing against any of them personally, all are decent, honest, hard-working men with England's best interests at heart. Tellingly none of Robinson, Ashton or MJ have gone on to prove anyone wrong with amazing success elsewhere. SL is probably the best of the bunch. I know he is highly regarded as a coach and I believe that in the right circumstances he would be a great coach at international level. However, he came in having won nothing of consequence but having impressed with how he talks and writes about the game. He has been crippled with indecision over his best selection, clearly scared to lose and only picks exciting attacking players when forced by injury, his backroom team has been utterly shown up. The issues have built up and up. I was absolutely mortified when the lessons of 2011 were not learned. The RFU had built up to that debacle with bad decision after bad decision. Picking MJ was the nadir, his regime was a shambles: dire play and awful in every way. Yet they went and did the same stupid thing again, picking an RFU inside man. It didn't work before and it didn't work this time.
Anyone defending Lancaster, and I know there are many, should consider the impact that a quality, experienced coach and back-ups can make. Take the Irish. Widely believed to be drifting under Kidney, brought in Joe Schmidt - two 6N in two seasons. Australia were in freefall a year ago, McKenzie resigned, 7 losses in 7 games. Everyone thought they were certs to go out in this pool of the WC. Chieka comes in and brings in Ledesma and bingo, wins the RC and is looking pretty good in the WC. Neither man has miraculously inherited some undiscovered new players. Both had the same pool as their predecessors and both turned things around.
If NZ had only won the RC once in 12 years and watched their bitter rivals win it over and over would they continue to select identikit coaches. A wise man once said "the definition of madness is trying the same thing again and expecting different results". The RFU are entirely at fault. Their frankly stupid method of choosing coaches is amateurish and has inflicted huge damage. It has also seen England fans endure over a decade of substandard coaching, tactics, selections and performance. They have huge financial resources and England must be a tempting job. Imagine now, any improvement would be greeted with rapture in English supporting circles. A coach who could deliver a Grand Slam would be chaired through the streets. The players are there, the resources are there, the support is there, it just needs a coach who can make it happen. Lancaster has to go, he was given a remit to prepare for the WC. You could try to argue away the butchered 6N he has presided over ("it's too soon for them", "they will learn", etc) but his task was to prepare a squad that could go deep into the WC. He has been entirely unable to deliver anything close. Nothing can excuse this shambles. I know it was the "group of death" but a man who is still unsure of his centre pairing after three years and brings in, effectively, two uncapped players at the last moment, still using the pre WC warm up games to pick his squad? That was a man who was never in control, who never had a genuine plan or process. The outcome was sadly predictable. The RFU need to take a bit of time, pay Lancaster off and this time, this time actually get it right. Identify the best available coach with genuine experience of top level rugby, at least Guinness PL and preferably across more than one country. Foreign if necessary, and it almost certainly will be. Offer him a great deal (and they can outpay any other union). Get him the best coaches, don't hobble him with inside men. I don't know who that man is but someone of the calibre and pedigree of a Gatland, even Chieka who had coached all over the world and won things everywhere. They should hire recruitment consultants or some sort of expert panel as their own processes are so flawed they cannot begin to deliver results. Lancaster cannot be continued with but if he is for some unfathomable reason then at least get shot of Farrell and Rowntree who have both also failed dismally. I don't hold out much hope, indeed the pessimist in me fears the job being given to Farrell, I genuinely wouldn't put it past them.
