The calf impacts Rodgers performance even in subtle ways. One example:

Packers final drive, after Rodgers scrambled for 12 ("normal" Rodger would have gotten more than 12) it was clear that his leg was bothering. He hopped and skipped the last four of five steps of the run. Next play, 1st and 10 from Seattle 36, play breaks down, Rodgers releases to his right, with a fair amount of room to run, and Lacy in front of him. Rodgers clearly does not want to run, and shuttles an awkward throw toward Lacy just as Lacy turns to block, thinking Rodgers will run. Pass falls incomplete. "Normal" Rodgers keeps in that situation and picks up a decent gain. Instead, it goes as an incomplete pass.
