Glad someone actually watched the game. Too many people just look at the state and immediately assume he didn't try or he should be replaced, but hey, that's what fantasy football does to people.
There were 3 or 4 people in the backfield every time he touched the ball. Even the best of runningbacks wouldn't have gotten much more than what Johnson did today. The offensive line has been one of the worst in the league in run blocking ever since Kevin Mawae left after 2009 (2000-yard season). Johnson's speed has taken a hit since then, but the line just isn't the same and misses the nasty streak it used to play with without Mawae in there. Hutchinson looked bad, Harris is beyond useless in both faucets of the game, Velasco was making his first career start lining up across Vince Wilfork and even Roos was getting his lunch handed to him by Chandler Jones.
Some of the blame can be put on Johnson, but most of the blame should be put on the people in front of him and you all would see the same if you actually watched a game.
