Playcalling. People were expecting Caldwell to change the offense in 6 days. Look at the plays he called today. Things we haven't seen all year long. Short slants, rubs, hell a WR screen! Things that got the ball out of Joe's hand faster, and as a result he got in a rhythm and was accurate. They rolled him out and moved the pocket when needed. That opened up holes for Rice and Pearce to run through, and they bounced outside when needed.
Caldwell put the offense in position to succeed, and the players responded.
