Of course Mark Wilson is doing more work - people tend to chip in during periods of adversity. The club has hired a recruitment lead. Baraclough is hospitalised. What more do you think the club should be doing in the circumstances?
And do you not think there's a strong possibility that the club made Bannigan an offer, possibly reduced from last season, and Bannigan then decided to have a look elsewhere? Essentially two different opinions of his value. And if this is nearer to the truth, your assessment of his worth appears to be pretty much in line with the club's.
There's always got to be a scapegoat - can't point the finger at the head coach at the moment, so let's blame the board for everything.
