OK... I guess I'm not convinced that this was a scheme change, vs. a result of McCoy's better ability to read the defense and make quick decisions and throws post-snap, rather than waiting for receivers to become visibly open. Those same plays might've been there for Murray to make, but he may just not have been making them (as @BritCard has illustrated repeatedly).I thought it was clear, but I will re-explain. There was a definite scheme change to have the ball out of the QBs hand as quickly as possible. The stats have been published already.
