Johnathan Joseph: C
Don't let the numbers fool you, as they easily can. Although it looks like the Texans shutdown Colin Kaepernick, the truth is that the 49ers hardly even threw the ball.
And as a result, it looks like Johnathan Joseph had a phenomenal game. But the opposite it true. Joseph, who looked like Kareem Jackson in his rookie year, refused to turn his head and identify the ball in mid-air.
That is a major problem for bad cornerbacks, and the Texans cannot afford for Joseph to fall into the destructive habit of refusing to take his eyes off the receiver.
Kareem Jackson: A-
Unlike Joseph, Kareem Jackson had a very good game. While the 49ers rarely tested the Texans' secondary, Jackson held his own and didn't give up any major plays.
Brice McCain: C-
Brice McCain continued his season of terrible performances in this one.
First, McCain was called for defensive holding that extended a 49ers' drive. And then he failed to cover Vernon Davis when he was lined up in the slot, allowing Davis to get wide open and haul in a 64-yard touchdown reception.
In a league that places an increased emphasis on passing the football, McCain is becoming one of the Texans' defensive liabilities.
