It's not just that. Bench players who play big minutes (Kevin Martin, JR Smith, Jarrett Jack, Jamal Crawford, etc.) will come in with like 3 or 4 minutes left in the 1st, and then he'll sit right back down a minute later. It's ridiculous. Plus the situation with the CPU not caring about foul trouble.
There's no fix for that unless 2K addresses the issue themselves for 2K14.
