Have in mind that since this thread was opened, the coaches in BB have changed. An old 9-10 coach is now equal to a level 5 coach, old 7-8 is equal to 3, and so forth. Levels 6 and 7 are new, and they work very slightly better than an old level 10 coach.
what does that mean? how can coaches "level up" and where can i see that coach level. also what importance does a level is for a team?
