Good fundamentals was one of the main reasons the Chiefs looked like a potential playoff team during their 5-2 start. They ran the ball better than anybody, which requires solid blocking, and defended the run well, which meant sound tackling. But they began to revert to some bad habits in recent weeks, resulting in key losses at Oakland and Denver. Not surprisingly, Kansas City had its two worst rushing performances of the year in those contests. To correct these problems, we hear head coach Todd Haley decided to run practice this past week more like training camp, putting players in pads and focusing on the core fundamentals that the club executed so well during the season's first couple of months. He even said that he noticed the players enjoying themselves on the practice field more than they had in some time. Haley and Co. hope that this will translate to game day as the Chiefs suddenly find themselves in a tight AFC West race.
