His win ratio isn't superb but it isn't the be all and end all it depends on who you manage for example Ardley win rate is only 33% but you could argue some of it is in league one and he is at a small club resource wise.
If we want a manager with 45-50% win rate we would need to take a real chance on a non league manager like Lincoln did with Cowley but they were non league at the time.
Not a dig at you Smiffy like I say not be my number one choice but if it is him then we have to back him.
