Yes. The Special Skill Playbook Training will let you learn plays faster, but you have to learn the seminars first. Here's a little trick I learned to learn and master the playbook in preseason-
1. Supersim the 1st Half of the 1st preseason game, getting each play to Learned status you can.
2. Quit the game at the end of the 1st Half.
3. Play the 1st Half again. Keep doing it until you get the entire playbook Learned. It takes a while, but it's worth it.You'll retain the previous game's play knowledge every time you do it.
