I have yet to see this and it doesn't make sense if that's how it's supposed to work.
Nowhere else in the game do you have to adjust the pieces to make the whole picture change. You adjust sliders and settings to reach a desired effect, not the other way around.
Besides that, that means I would have to sign a bunch of players who don't fit my scheme just to "maybe" get the scheme to change? But again, I've never seen a scheme change.
For example... I had a Power Run, Base 4-3 scheme with Jeff Fisher. I retired him and took over the same team with a created coach using the same schemes. Magically the team schemes had shifted to West Coast and Spread... what???
The players were the same as before, so that blows the theory about players making the scheme right out of the water.
This whole scheme issue is really getting on my nerves and the misinformation about it isn't helping matters.
