DC Mike Zimmer used new, complicated schemes during this week's OTAs. The two-pronged effect not only showed who could handle the mental workload defensively, but challenged QB Andy Dalton's ability to decipher. "The more times he gets to see these same looks and different looks he's going to get from coach Zimmer, the better he's going to be and the better schooled he's going to be," OC Jay Gruden said.
