Example of teams not wanting to trade for him due to toxic morale

Morale determines how happy or satisfied a player is. Poor player performance leads to worse morale, while good performance leads to good morale.
Low morale means receivers and running backs are more prone to fumbling. Also defensive players are more likely to miss tackles with low morale.
Morale Ranks:
Exceptional: 90% or higher
Great: 80% or higher
Good 70% or higher
O.K.: 50% or higher
Poor: 40% or higher
Bad/Angry: 30% or higher
Toxic: Below 10%
When a player has a toxic morale, no one would want to trade for him, and he won't accept a contract extension until you boost his morale to at least bad morale
