49ers film room: Offense’s opening drive vs. Vikings starting defense
By Chris Wilson

2nd-and-8 at SF 36
The 49ers line up in 21 personnel, with McDonald off the line of scrimmage, and both wide receivers in plus splits:
McDonald motions toward the near side of the field before motioning back to his original position:
The Vikings switch to a single-high look, as the strong safety moves into the box and linebacker Anthony Barr shows blitz; Barr will be Juszczyk’s responsibility if he rushes the quarterback:
Barr blitzes, and Juszczyk struggles to keep him out of Hoyer’s face; Hoyer is forced to make the throw before he hits the back of his five-step drop:
Luckily for Hoyer, he has an open receiver in Garçon. Here’s Garçon as he waits for the snap:
Garçon’s hard step to the outside has cornerback Trae Waynes corncered about a potential fly route, since the corner has limited help over the top.
Garçon has Waynes flipped around when the receiver cuts inside:
Garçon catches the pass and looks to gain yardage:
Garçon is taken down after a 16-yard reception and another 49ers first down.
Great move off the line by Garcon. Good thing, because Hoyer has to throw the pass before he hits the back of his drop #49ers pic.twitter.com/aYzYbkWw74
