I have not read all the other comments. Maybe someone has already said this but:
I think the #1 issue this team is facing is unfamiliarity/chemistry. Think about it. Half the team did not know each other six months ago. It takes time for teams to gel. Throwing a bunch of transfer players (that don't know each other well/have never played together) together is not the most ideal situation. They don't know each other's tendencies. There is no trust. No familiarity. No chemistry. It's evident at every position on the field. At times, this team looks like a summer time backyard/play ground/neighborhood football team. IMO, this explains the disorganization, individualism approach to the performance we have seen this season.
Teams need time together to learn each others strengths/weaknesses/tendencies. This team doesn't have that. Transfer players are hired guns and are a temporary fix. Not a long term solution.
