The San Diego Chargers will receive the ball to start the second half, and could end up with a lead over the Kansas City Chiefs if their offense can be as effective as it was at the end of the first half.
The Chargers offense hasn't actually been that bad, Keenan Allen has over 100 receiving yards through 2 quarters, but the Chiefs defense has come through with a few stops and penalties on San Diego haven't helped Mike McCoy's group (for the second consecutive week).
The Chargers defense has really struggled, and seemed to get worse as Andy Reid and Alex Smith realized they could throw downfield with ease. John Pagano will have plenty of adjustments to make at halftime.
Actually, whichever coaching staff makes better adjustments at half time will probably end up with the win. However, Mike McCoy has already left some points on the board by punting in FG position and kicking a FG on 4th & 2.
