I've been tweaking player tendencies a lot more, trying to get the league as a whole to shoot more three (on average in 2K the CPU would attempt about 25-35 threes while the NBA in real life was creeping into the 40s). I like to think it meant those guys had some good summer workouts and were ready to go
I definitely had the injury slider too high on the first day of the season, turned it down a little. Tried to emulate the idea of some guys not coming back fully ready, I remember some early season injuries (Jeremy Lin and Ricky Rubio come to mind immediately), but we'll see how teams navigate.
