In Part 1 we learned two key lessons:
1) Pete Carroll is willing to risk a single timeout on a whim, wins 45 percent of his replay challenges, and yet remains extremely competitive with his NFC West peers since joining the Seattle Seahawks in 2010, because...
2) Good coaches didn’t usually win more than half their challenges either. Jim Harbaugh and Sean McVay scored lower than Carroll; Kyle Shanahan and Bruce Arians higher.
Based on the second discovery, I threw one theory into the ring on Monday: success with the red flag is not connected to overall football game success.
