Maybe job had a bit to do with team morale ending up being shit I remember him putting a picture on instagram after the crewe game with arma maddison and I think Murphy with a comment like looking for self praise or something like that.
I think it's more the other way around. Players that have been trying hard have been dropped after good performances or not been given much of a chance at all. JOB, Rose, Tudgay, Lameiras, Henderson etc.
I think if anything the loss of morale is due to Mowbray playing the same players that are consistently under performing. Ricketts, Fleck, Murphy, MAF etc.
There's no fairness in the camp at all. I really feel that Mowbray's man management might not be as good as people think it is. I get the impression he has his favourites and this may cause friction as a result.
The 'we can't win every game' was a bit of a loser comment as well. Sometimes you need a horrible bastard who's going to let them know when they've not been good enough.
