Sometimes I'll randomly look up NBA 2Kbstuff and stumble into a reddit thread. The most recent one, a few days ago was "Why is MyPlayer's morale listed as Outraged??". They then list that they're like, a starter, all NBA, and won the Finals in their first season, so theyre confused.
My immediate guess is that the player thinks they're underpaid, because someone performing like that and getting basically pennies what they're worth is No Good. Plus I doubt My player, your created career mode player, uses a different morale system than the other modes because I don't foresee 2K doing that.
It's great if I'm right. They basically modeled how everyone feels at their job. Go above and beyond and get fuckin nothing for it. At least in the NBA you're guaranteed a raise and winning certain awards can make your max salary larger.
