I'm fairly confident that they are reversed; but still very much in small sample size mode. I can really use some help here and some observations.
Bear in mind....I am absolutely NOT advocating the use of generic playbooks (which are too generic), just changing the schemes. The schemes alter the types of plays/formations the CPU uses within the confines of their PBs.
I tested a couple yesterday;
initial impressions:
Vertical Offense: lots of four vert plays and 'shot' plays
Spread: 3-4 WR sets, lots of passing and short patterns (like meshes). Reminds me of an air raid offense. Tested with KC and it really was tough to stop...they passed over 60% of their plays; also saw a few (rather effective) zone read plays.
West Coast: Run heavy offense, lots of 2 TE sets (if available). As stated, more reminiscent of run heavy.
Power Run: balanced offense but a bit more geared towards the short passing game, solid variety. As stated, more reminiscent of a west coast.
To be tested:
Balanced: I have no reason to think it is something other than balanced..most teams use this by default
Zone Run: assuming it is geared towards zone run plays
