A proposal like this wouldn't surprise me at all. But if we were perceived to have moved to the suburbs of Birmingham, even if it is only 9 miles, it would destroy the identity of the club. Travelling distance isn’t the point – we can’t go to a different town IMO.
I guess you could argue that some parts of that area (Meriden/Balsall?) are on neutral territory between the two cities, so maybe BCFC and CCFC could just about swing a ground share proposal if the location was just right. But anywhere the wrong side of the M42 is surely a complete no-no from Coventry’s perspective.
Hopefully those who have been saying that Wasps can move 30 miles in and out of London without damaging their identity won’t be arguing in favour of that regional franchise model for CCFC. They became “portable” without a unified or fully committed fan base, and the same would happen to us. I can just hear Fisher saying it now - “Coventry City have always drawn support from the wider West Midlands area, and this move to the NEC will enable us to further that appeal by offering our valued customers an unrivalled matchday experience, whilst growing the club’s essential revenue streams”.
A mega-modern stadium has its appeal of course, and the prospect of buying into it would make the CCFC "franchise" more attractive to investors. But it would most likely be a recipe for another divisive shitfest, and I’m pretty sure fans of both clubs would prefer to stay where they belong.
