Remember how some teams simply had a generic 3 out or 4 out freelance system? I'm taking it to mean that all 30 will have their own team specific freelances.
Definitely cool. 2 things I do hope for this year is that the team specific ones from 2k16's lesser teams such as the Sixers motion were expanded upon (we all know some awesome detail will go into the Warriors and Spurs swing).
The 2nd thing is I hope that freelances are no longer tied to the team. Yes you can change yours in game, but not the CPU obviously. And say 5 years into a MyLeague, a team will still run the same system, no matter if they are on their 2nd or 3rd different coach.
