Wasps also have to find a ground. Whilst there have been rumours, nothing has been confirmed. Wasps' new owners were at least approved fit and proper, whereas WW's US owners/backers were not, and are still not. For Warriors, getting that approval of the US backers is the problem.
For us, we actually need some backers with real money. The provision of a ground is not, as far as I can see, part of the deal.
Warriors says they are not committed to elite rugby (ie Prem or Championship), but that they want to play rugby. Rugby League anyone?
