The only way one can know if they're right or wrong, in this case on how the offense runs and how the team responds, is to put it to the test. I think we're a different team with Sam in there as opposed to Shane. It has to do with moxie, personality, etc. Sam attacks the job. Shane seems to try to survive it. I've just noticed. Maybe I'm wrong.
I feel like the plays develop way too slowly when Shane is in there. Its almost at HS speed. I get the impression when Shane passes, certain things have to be in alignment for success to happen. Perfect route, protection, etc.,
Only way to know is put Shane out there and see what happens.
