The Houston Texans were early-season Super Bowl favorites, to say the least. Despite a strong start early in the season, in which they only reinforced those pre-season Super Bowl predictions, the Texans appear to have fallen from their seat as a superior AFC team.Over the last two weeks they have been challenged by not-so-challenging teams. Both Jacksonville and Detroit gave Houston a real run for their money. So then, Houston, do we have a problem? I have drawn up four problems with the Texans at this point; four reasons that they will not be able to compete with other AFC power house teams.
