The Texans will be watching the AFC championship game at home because they turned the ball over four times in the divisional-playoff loss to the Ravens. And while rookie QB T.J. Yates deserves much of the blame for throwing three interceptions — all into double coverage — the costly turnovers magnified perhaps Houston's greatest remaining weakness: a lack of a legitimate No. 2 wideout who occasionally demands double-teams. Yates was looking for a bracketed Andre Johnson on all three picks because WRs Kevin Walter and Jacoby Jones were virtual nonfactors. In two postseason games, Walter caught three passes for 36 yards, Jones had zero catches (and a costly fumble on a punt return) and no other Texans wideout caught a pass. The WR position will be the Texans' top offseason need, we hear, and could be the one area holding them back from becoming an elite offense.
