I stopped insulting individual players a few seasons ago when it occurred to me that it's the manager who signs them, selects the team to play each game, decides on tactics to be used, makes the substitutions and blames everyone but himself for under performing. Today I don't think you could single individual players for that performance. To me everything was wrong, there was nothing positive about the whole team performance. Lack of motivation could be the problem. Do remember that on Tuesday night the performance was crap as well. Have the team lost confidence in the manager, is he not motivating them, has the manager lost the plot, has he reached the limit of his ability. Swapping players around, playing them out of position is unsettling. At this time the team is not very good and losing to Leek is more likely than winning.
To sum up, well I think 90 mins of a home game without one attempt on goal sums it up, it's not surprising the crowd were quiet. Also needs remembering that it was not just one player that under performed it was almost the whole team, almost.
