The most enigmatic potential head-coaching candidate is one that is currently still employed.
While the Texans face the Raiders today in a playoff game at 4:35 p.m. ET, six teams are engaged in a competition to find a new head coach.
And many of them appear to be waiting on the future of Houston coach Bill O'Brien, according to several sources.
The third-year Texans coach has won the AFC South two years in a row -- with a revolving door at quarterback -- and is searching for his first playoff win today.
