No-one is saying we wouldn't 'find' another manager. The debate should be around how good a job Jim has done compared to someone else. Could someone else put up with all the off-field trauma that we have been through in the last few years? Players (& management) repeatedly not being paid? Jim apparently agreeing to re-sign Devitt & Miller, only for a director to decide to reduce their pay, and offer them less than they'd been on the season before? No-one knowing who owned the club? No training facilities? Ever reduced budget? Best player sold for less than he was worth in order to pay players? etc... etc... etc...
You mention Port Vale as an example. They've had nine managers in the time that we've only had Jim. In that time, they've had one promotion & one relegation, last season finishing in 20th place in League Two despite an average attendance of 4,583.
Changing managers doesn't necessarily bring success. Chopping & changing managers frequently brings failure. Look at Notts County. Surely you aren't suggesting that we're as big as County or Vale? Look at the clubs that are bigger than us but been relegated while we've stayed up.
What do you think we should be doing on our budget & facilities?
I agree. Also, we have some half decent players this season.
