Firstly, get well soon Bill. Cancer is something that's affected family and friends of mine and some are not here as a result.
Secondly, surely there's a responsibility on the club/owner here. If he's still working until the point of his operation and is expected to now have a long recovery period, who's stepping in and giving him the time he needs to recover?
For the record, I think he run his time long ago based on nothing but the performance of the club commercially and performance on the pitch but there seems to be a vacuum in proper leadership to protect all parties.
