1. The Chiefs run defense was once again really good allowing only 3.5 yards per carry. The defensive line is extremely strong and linebackers were attacking their run gaps aggressively. The 49ers took advantage of this by using play action to suck the Chiefs linebackers up to the line of scrimmage and then passing into their vacated zones, This happened with each string of Chiefs linebackers and helped the 49ers go 9/14 on third downs. The most frustrating part was that this happened repeatedly on third and medium or long, where the offense is not usually looking to run.
