Do the RFU actually have the resources to take over the clubs?
I highly doubt it. If the club financiers pull out then the game in England collapses as far as I can tell.
Our best players will **** off to France or League.
I think yes, but not with the ill feeling it would cause.
If gates stayed the same, fans kept spending the same, then ok the RFU would have to go into a lot of debt to sort things, but between getting all the profits back - there are some around - and their own incomes, it would be manageable. It probably wouldn't be a great move for English rugby, and some clubs in particular would suffer - here's looking at you Saracens - but I think it could be doable except there's no way you'd keep the same gates. That boat has sailed, which is a great shame imo.
The RFU will keep very quiet and hope this can all be resolved without them having to upset anyone.
