Still haven't heard the word on Andre Johnson for this week. I would never have thought I would consider sitting him, but I'm not even sure he's playing. If he plays, he's going up against Asomugha.
My choices to replace him are all playing late games, so it helps that I can wait to see if he's even playing. Choices are:
Kevin Walter vs. Raiders
Louis Murphy vs. Texans
Johnny Knox vs. NYG
If AJ plays and draws the attention of Asomugha, then Walter might be okay. If AJ is out, then Walter gets shut down. Murphy has a good matchup against Houston's poor pass defense. Knox has a tougher matchup.
My gut says go with Murphy no matter what (unless he's scratched). If he's out and AJ is playing, then go with Walter. And finally, if AJ and Murphy are both out, then go with Knox.
