As someone who played in seasons 3-6 before dropping out in disgust at all the little things that didn't work, the fact the sub patterns are still a mystery is discouraging.
I had hoped to see improvements in most areas, but no. Very little has changed for the better, in particular the sub patterns. There does not seem to have been any change in this at all.
What is so hard about adopting a system similar to many PC basketball games in which each period is divided into four 3-minute segments and the coach puts in a name for each position/time slot for each period? There can be a 'blowout" option for the fourth quarter, too. Injuries and fouls effect this slotting, but it is followed for the most part.
Take a tip from the realm of 10-year-ago PC gaming and adopt this option.
