Steve Wilks came out of the bye week with much-needed changes. Javon Kinlaw started the game as the fifth defensive lineman as opposed to a third linebacker or fifth defensive back.
Then, on second down, Ambry Thomas, yes, that Ambry Thomas, came onto the field when the Niners elected to go into their nickel defense. Arik Armstead’s sack on third down forced a three-and-out.
After the Jaguars failed to gain a yard on their first drive, the 49ers marched 57 yards in just over two minutes after George Kittle was wide open for 29 yards.
