I'd go if we relocated, if they want to move 50 Miles South then I would be truly over the moon (Not as much over the moon if we stayed at The Ricoh) let say for example Sixways Stadium, 12,068 Capacity within the 50 Mile Radius that the Football League require, groundshare with Worcester Warriors!
Not quite sure where you got the 50 miles from, but the regulations around ground sharing are here:
http://www.football-league.co.uk/regulations/20120702/section-4-clubs_2293633_2125725
I suspect the key clause is "13.7.3 (ground sharing might be permitted if it) would not adversely affect such Club's Officials, players, supporters, shareholders, sponsors and others having an interest in its activities;"
I'd have thought 50 miles might be a bit of stretch to fulfil that, in truth.
Regardless, what is clear is that the FL would want to see a detailed plan for how, within a few years, the club could move back to the City. If that wasn't plausible, they wouldn't let the club move outside the town. (This according to Bob Ainsworth's report on CWR, of his meeting with the FL today).
And the Butts is surely a non-starter. I go there fairly regularly - one small (2,000?) covered stand, three open sides, and a few open turnstiles. Parking for a couple of hundred. Even if it could be redeveloped hugely in the three-month close season, there is no way that planning permission would be granted within that timescale - and more likely that they'd never get it given the area and history.
Personally speaking, I think the ground share thing is a complete bluff. Even if they found a suitable venue there's no way that SISU could put together a plausible plan for moving back to the City anywhere other than the Ricoh.
How could SISU fund a new stadium, where would they build it, and how likely is it that the Council would grant them planning permission after all of this? It's another bluff, and a fairly pathetic one, imho.
