The Kansas City Chiefs got a big win over the Oakland Raiders on Sunday and it is no secret that linebacker Derrick Johnson was a big contributor to the win.

While Johnson did have a very good game, his performance was not actually as solid as some are claiming.

What most folks remember from the game is DJ’s play on the goal line. With the Chiefs leading 14-0, Raiders RB Michael Bush broke off a big run. It looked as though Bush would score until Johnson caught up with him and pulled him down just yards from the end zone. The Chiefs then stuffed the Raiders four straight times and Johnson was responsible for three of those tackles, and he assisted in plugging up the hole on the other.

It was a very impressive series of plays for Johnson and he helped the Chiefs keep the Raiders from getting back in the game. When the day was over, Johnson contributed 13 tackles. He also had one QB hit and six stops (offensive failures).

While Johnson deserves credit for all the good he did, there was a major hole in his game that nobody is really talking about. According to our friends at Pro Football Focus, Johnson played the run very well Sunday but struggled mightily in pass coverage.

PFF graded Johnson+2.0 for the day bit he lost major points for his pass coverage, where he graded at -1.4.

According to PFF, Johnson was in for 70 snaps and 30 of those snaps he was in coverage. On those 30 snaps, Johnson was targeted seven times, allowing six catches for 67 yards. When throwing at Johnson, Oakland QB’s had a QB rating of 106.5.

So Johnson had a great game but certainly not a perfect game. The Chargers are sure to notice this when they break down the film. The Chiefs will need Johnson to tighten up his coverage a bit.
