No, they aren't minor details because these would have an important impact on the decision, so I'll need answers before I could make a call. For example, the terms of the ground share would be integral - if it involved us playing on consecutive days, that might be unacceptable. Likewise, the rules on what players we would be allowed and how it would be financed in the short and long term - integral to the decision.
Not least, of course, planning permission. That takes weeks to get through and we might be obliged to contribute towards road rebuilding, etc. How is that to be financed? All these would have to be considered now if we were to be able to ground share in, say 2016.
Also, what's the long term purpose of this ground share? Is it to redevelop both Carrow Road and Portman Road? Why do they need redeveloping?
It would be great if you could answer these questions, then I can give you a definitive answer
