Jaysus if you know your schedule for the entire year in January you’re a better man than me! Endless weddings stags house warmings etc etc popping up as the season goes on. I do agree with your point about over stretching however. A very common phenomenon is that of the squad player who doesn’t get a run on the Saturday night. Being asked to go home, stay in, and tog again on Sunday seems too hard an ask for some, leaving the team below struggling 12 hours later.
Friday football for lower leagues would be perfect as a trial at least. Availability of pitches, refs etc would be the obvious counter argument, but I think its worth a shot.
