This turn around has had more to do with McCarthy tightening up the leash (slightly and often temporarily depending on offensive flow) on Rodgers inclination to improvise and the receivers' ability to separate quickly vs. man coverage than any "creativity" he gained, or lack of it previously. He's a creative offensive mind, which was partially what caused some problems during the drought. The innovative "second level" attack is his brainchild, but like all innovations, there are often bumps in the road and adjustments to be made.

Rodgers and the whole offense benefits from some structure early, and then he can open up the second level attack once they get things going. The full arsenal of healthy receivers makes all the difference too.
