I would imagine he's not daft enough to realise there's no real money to be made in rugby. Sepella once said they were as high as they could get and still losing money, I think this is true. He did well selling Newcastle but I can't see he'll be able to make that kind of money with a Rugby club, even if they ended up being the best in Europe, the TV money and sponsorship isn't comparible.
If it's a choice, think I'd rather have Ashley than the NEC group. With the NEC, we would always be tennants. With Ashley, there's a chance he would take us on at some point and eventually sell us as a package (once SISU realised there's no real other get out - believe they did say they were open to business and encouraged someone to buy the stadium?) If we had some investment and were successfully promoted, could be the kind of package that would be worth a few bob.
