yes but in my case, almost all my players have bad form and not just the one.
I see now that I replied to you without bothering to check out your team.
The whole reason your players are in bad form is because you only have 10 players and they all play 3 games a week, so they are too tired to be in good game shape. If your players play 80-90+ minutes per week their form will suffer, and your team is a prime example.
You have a few options:
1. Buy at least 2 more players. This will help spread out the amount of minutes each of your players plays each week, and could help their form recover almost immediately. These players could also come in handy when injuries happen to your current roster.
2. You could stop playing scrimmages, thereby reducing the amount of playing time each player spends on the court each week. However, this could hurt your training.
3. You can train form almost every week. Your players will improve in game shape (i think), but your team likely will never get much better than it is right now.
That's all I can think of now, hopefully that gives you some better information (although someone else may be able to think of more options).
