The way I see it, the Council is strapped for cash, but Odsal would be worth a decent amount of money to various developers. It would be enough to build a community stadium. I don't see how anyone could complain if the Council took that route; especially as the site (Richard Dunn) is already earmarked for clearance (which won't be cheap) and so far as I know, there's no plan for what to do with the site later.
In my mind I have written off us ever returning to Odsal, because it is simply impossible that anyone will come up with the necessary money to upgrade it.
My only questions would be to the RFL; they loudly proclaimed they were acquiring the lease to save the iconic Odsal for posterity, but it already needed a major upgrade, and you weren't saving anything for anyone unless part of your plan was to finance the upgrade. If there was such a plan I'd be amazed. If there was no such plan, then the RFL have pointlessly acquired a lease which is now a millstone, as they posed as saviours for rugby league, but it seems obvious that won't happen, and that Odsal will never see RL played there again.
