Here's the play that put the second to last nail in the coffin for CAR. It also made the bs penalty on Skuta a non issue.
Below: 49ers come with cover 2 man under. Bow is on the TE, Willis is on the RB. Everyone else is manned up: Brock (top), Cox (slot), Brown (bottom). In this picture, the ball was just snapped and there is one 49er who has reacted before anyone else. Before anyone else on the offense for that matter.
Below: 49ers will use a stunt with Justin. It's vital that Brooks and RayMac execute properly to collapse the Oline inwards, allowing Justin to loop to the edge. Brooks and RayMac will attack the inside shoulder of the RT and RG, respectively.
Below: Cam's first and only read is Olsen the TE. With Bow playing inside leverage and a safety over the top, Olsen is not open on any kind of vertical route. Cox has defeated the crossing route by the WR.
Below: Same moment in time as pic above. The stunt works and Justin has a clear lane to the QB. Cam never takes his eyes off of Olsen the TE.
The line stunt.
Cam foolishly makes the throw anyway. On a 1st down, after getting a very beneficial PF call for roughing the QB, Cam throws away any real chance at a comeback by forcing the issue.
Bow does not care to block. It's a done deal.
