My penny worth and I think it's a combo of things:
Not enough pace in the team to get up the pitch quick enough - this has been an issue for a while, so I guess recruitment does need to take the brunt of that one.
Not enough desire in the team - other teams in this league, even lower than us, have exceptional work rate, and will be on the opposition from minute 1 even from the lads up front - as good as Hawkins is at other things, he doesn't do this, and neither do the midfield. It means we don't cause mistakes in the opposition, we don't contest 50/50's and win possession back much - we just look sluggish, we also don't drive at teams when we are in possession and stretch them. Hard to know who to apportion blame to here - the players clearly need to find it in themselves more, but it could be an element of us being set up like it, or them simply not having the raw attributes to do it.
Part of me thinks the above is born out of signing a reasonable amount of older lads in our hour of need last season, and them being happy in league 2 earning well.
No confidence - even the lads who have a lot of what is needed in their lockers already, take an extra touch etc, when shooting or attempting to be creative.
Lack of anyone in the BMS - this only goes so far though, under Clemence (home and away) we haven't scored in 17 first halves, not every game is played facing the BMS first half.
I think a squad overhaul is needed personally, my gut feel is Clemence is doing and trying to coach the right things, but many don't care enough or don't have the raw attributes, I would focus more on an up and coming squad hungry for success and trying to forge a career, rather than signing lads who have already had one (a few good older experienced heads aside, like Ehmer or Morris etc).
It is a huge testament to our defensive players that we are 7th.
