Purdy's second completion (0:19)
The Niners came out in 12 personnel (1 RB, 2 TE). Purdy recognized man coverage pre-snap as the Kansas City defender moved with Jauan Jennings during his pre-snap motion. Juszczyk was lined up off of the line of scrimmage to the right of Kittle. He ran a 4-yard out route while Kittle ran a drag across the field underneath. This cleared out the middle of the field for Christian McCaffrey to free himself up on an angle route out of the backfield, inevitably beating the defending linebacker for an easy first down.
