Wes Welker vs. Houston's defense
We already touched on Houston's banged-up secondary, but the real stumbling block for Patriots wide receiver Wes Welker (pictured) might be the play of the Texans' defensive line. Houston excels at batting down balls in the air, which could wreak havoc on the short passes Welker is so good at catching. Welker may be open, but it will be interesting to see if Tom Brady can get him the ball. In addition, Welker tore his ACL the last time he faced the Texans, which could be in the back of his mind.
