My sense based on descriptions is that this is very close to the Shanahan offense which historically is a pro offense using the zone running scheme as a core which is intended to stretch the defense horizontally and then the passing game is built heavily on play action.

Thus, the ACTUAL PLAYS we will see may strongly resemble the plays we've had in the past, at least on the surface, with some exceptions (but maybe not as many new plays as people expect).
However, how it will be IMPLEMENTED should see more wrinkles:
- Going from maybe 5% of plays with motion to 50% or more, in order to confuse and reduce the time defensive players have to process their responsibilities and communicate changes amongst themselves
- Going from few or no RPO's to a higher mix of RPO's, likely starting at 2-5% of plays as RPO's and working up to some higher mix (20%?) as the players gain more comfort with the playbook
- Willingness to take more deep shots especially out of RPO reads pre-snap, in order to keep defenses honest at minimum
These 3 things I think are the key, and should increase our ability to produce chunk plays, which in turn should loosen up the crowded boxes we've been seeing the last 3 years that hurts the productivity of our more standard plays (inside/outside zone mixed with gap runs and basic short passing game).
