'What play looks good on third and 20 from your own 26? How about let McCoy make magic? The 49ers rushed three and sat back in a zone. McCoy took a handoff off left tackle that would have been a 10-yard gain for 98 percent of NFL running backs. But McCoy made a jump-cut to the right. Niners linebacker Michael Wilhoite, in position, could only watch as Shady blew by him to the right sideline for 22 yards. First down. It allowed the Bills to get a field goal to end the half.'
