This season, the Houston Texans' offense and defense were not top-notch, ranking in the middle of the league. Not terrible, but also not outstanding, truly mediocre.
However, it was this kind of "mediocre team" that topped the AFC South, narrowly won the wild-card game against the Buffalo Bills in overtime, and unexpectedly swept the Baltimore Ravens in the divisional round, standing honorably on the stage of the conference finals, attempting to become the first team this season to defeat the Kansas City Chiefs.
...Why?
No doubt, football fans must be asking this question: Yes, why, why the Houston Texans?
