Last night in the NFC championship, the San Francisco 49ers trailed the Seattle Seahawks by six, 23-17, with 30 seconds left in the game. Quarterback Colin Kaepernick had led the 49ers all the way down to the Seahawks' 18-yard line. He took the snap out of the gun, set his feet, and released a flossy little fade to the corner of the end zone, where receiver Michael Crabtree had his hands out. And then Richard Sherman happened.
