Yeah, "schemes" are a good idea, but they aren't being implemented perfectly, and in cases like this, it's a bit of nonsense.
I can see a guy like Aso hitting FA as a cap casualty, but when it comes to say Suh or Miller, these are guys that any system can work with simply because of their talent level. I'd like to see top notch 4-3 DEs get a shot at OLB if a coach that runs a 3-4 takes over, or for the ratings to make it clear to the AI that a guy like Suh is going to be worth using in just about any system. Miller makes the least amount of sense considering he can absolutely play DE and OLB.
Hopefully they can keep improving schemes and building on it rather than scrapping it, and this would be a big step forward.
If a star player is going to get released for scheme issues or for the cap, it should be a storyline and commented on a lot by the twitter dudes. I would also like some of these really bold decisions where a franchise level player is cut to maybe put more pressure on the coach that makes that decision, ie make it easier to get on the hot seat or fired.
