It's becoming more and more blindingly obvious what should happen with the RFU. The profit they're making means that they must be running the business side of England very well, so someone's doing a decent job.
What has to happen is a total and utter separation of the England rugby setup and the rest of the RFU.
This needs to have a trusted overseer to be the director of rugby - no coaching role at all, not accountable to anyone and simply the guy in charge of appointing the Head Coach position for the seniors, Saxons, U21s etc. This is such a small job, it needs someone popular within the game but also with the ability to be ruthless when necessary.This person's job would be so minor they could do it part time/ from the other side of the world, and it might be better if they weren't English and didn't have any loyalties to people/ clubs in the English game.
With the senior team, then I'd say given all the people who've said no, Mallinder is the only option (I also think he's the best anyway). He must be contacted, and contracted, soon. If he accepts, then he must be given full reigns to appoint his own coaches. Hopefully a proven coaching team doing what they want to do, with a nice young team (who can be molded in the coach's image) will be far less of a shambles for England.
It's so obvious I'll be surprised if it happens.
