I think there are three reasons for the loss of form, number one obviously being the loss of JG's enthusiasm and drive on the pitch. The other two are kind of related, the covid lockdown the club went through plus the fitness of the squad in general.
From the start of the season we were as fit as every other team and were able to play them on an even playing field, we were near the top of the table on ability. The fitness we lack is stamina related, put simply, the whole squad have run out of puff. Year on year the squad will get fitter stamina wise, meaning the team will be able to play on that even playing field for deeper into the season. The way the head coach could help is by rotating the players, instead of playing the same team week after week This would not solve the problem on it's own but, it would help. The fact that we have a squad that doesn't get rotated in and out of the team, must mean that the coach doesn't trust them to be good enough, that being the case, replacing players with better quality players is what needs to be done.
