there are many different playbooks that don't have all the same plays. If you look at your head coach it will tell you the offensive and defensive playbook your team uses. :)
Oaah I finally found one way in which coaches are important : they give access to some of the playbook -
Thank you so much for sharing that info, and if you have a thread with more info (which prefrence gives access to which plays, etc..), that would be great !
Coaches hAve minimal in game bonuses added to players on the feild . They also, minimally effect the rate that the players gain ratings in specific skill sets. Both boosts are high lighted by the red area shown under the coach cards . The HC has the most effect then coordinators then positional coaches .
