More chance of back-to-back relegations IMO. League One can be an unforgiving place, especially for pretentious clubs with serious off-field issues.
The only Sheffield derby they'll be looking forward to in a few years will be against Sheffield FC the way they are carrying on. Might have to ground share with them down in Dronfield.......
As far as I know they are the same rules as in the Championship...an owner can pump any amount of money in he wants, usually as sponsorship....but it can't be recoverable as in a loan.
