The dust has started to settle after Saturday, and my overriding feeling is still frustration. Well, a number of frustrations. I'm not one for knee-jerk reactions, though, so I stay stick with the coaches -- for now.

A long hard review process is needed, so I wouldn't make any rash decisions over the coaches' futures until that is done. They will have learned long, hard lessons after this, and it's worth remembering that Clive Woodward was given time to build our 2003 team despite going out heavily to South Africa in 1999.

A review has to be done by a totally different board to the one that selected Lancaster back in 2011. That review is not just about the coaches, or the players; you have to go above that. What are the ideas behind this team, and behind the RFU? How did we end up with this coaching team? What is Rob Andrew's role in all of this, and what is he doing? There are people there that have dodged a bullet, and hopefully someone external can come in and look at the whole system from top to bottom to sort out the future of rugby in this country.

Yes, Stuart Lancaster has made some mistakes, and it shows. It's embarrassing not to get out of your group, especially at home. It's our worst World Cup performance ever, and it has come when we are hosts.

The biggest question mark remains selection. It has to be, on at least two counts: we weren't experienced enough, and some of our best players were overlooked.

Michael Cheika took over at Australia less than a year ago, and did so on his terms -- he said he wanted to pick his best players, and he did. So how has Steffon Armitage been overlooked by England? The guy is world class -- full stop. A policy that denies the team the right to select from all available players has proven to be England's downfall.

We have to scrap the ineligibility rule for players playing abroad. Rugby is a different beast now -- there is no loyalty because the players have short careers and need to earn money. I like the tradition of a bit of loyalty, but when there is money involved and you are treated like a piece of meat, you should be allowed to take the best wage on offer. If that is abroad, fine, as long as you're playing a high level of rugby.

Armitage wasn't getting picked over here, so he went abroad and made himself one of Europe's best players. Then we ignore him? Even though the move abroad improved him as a player? Ridiculous. If you're winning Heineken Cups and the Champions Cup and getting yourself on European Player Of The Year lists, how can we ignore that? It's not like he is a 12-hour flight away.

We should have brought Dylan Hartley back, too, after a slap on the wrist. We needed that maturity and experience on the pitch. I said before the Australia game that I was worried about a lack of experience, and it showed. Why did we call up Henry Slade and not pick him? Why drop Luthur Burrell and bring in Sam Burgess, who has been playing a different position for his club? He's a quality player but he's still green behind the ears.

Chris Robshaw is a good player, but he just didn't have a good World Cup. I don't know where you go with his captaincy now, but it's fair to say he had a seriously tough task. With no experienced heads around him, all the pressure was on Robshaw to carry England through a tough pool, play out of position and lead the team both on and off the pitch. He will get criticism, but I think he has a future with the side.

To be fair to England, the pool was a joke, and World Rugby can't let a draw be made that far in advance again. This is only the eighth World Cup, so we are still learning as a sport -- but rugby must ensure it is a lesson learnt, particularly with people talking about the interest levels dropping, and the income dropping, now England are out. I'm not using it as an excuse at all, I can't stress that enough, because Wales and Australia were better, but those three shouldn't have been in a pool together in the first place.

What you want from the group stages is a few big games, and a few surprises, but the excitement starts in the quarter final. Instead, all the excitement in this World Cup was focused on England's group, which isn't right. We barely even mentioned the other groups -- except for Japan's win over South Africa, obviously.

You've got to take your hat off to Australia and Wales, too. Australia's heads-up rugby was unbelievable on Saturday night. Geech used to say he just loved that southern hemisphere style. They believe that attacking rugby wins games, whereas we look at defence as a winning strategy up here. It really showed against Australia. It's a key difference, and another thing that maybe needs to be looked at in the aftermath of this World Cup.

As if to make matters worse, there is still the Uruguay game to go. How painful is that? These players are in for a horrible week. It's like a third-fourth place playoff, but worse -- a dead rubber at primetime on a Saturday night.

It's been a horror show of a World Cup campaign for England. What a way to end it.
