Not a tactical issue.
It's just the game deciding you had enough fun and makes you miss every chance or being unable to save anything.
Happens with everything in this game, just got to ride it out.
For example I've had zero problems with injuries my first two seasons then the third season half my team was out injured in the preseason and my tactics which have given me top spots aren't working any longer. And no it's not because of reputation making team play more defensively because we have had the same reputation for three seasons.
