I would struggle with this decision a lot. If it is not a PPR league, I would likely sit Housh because he just doesn't seem to find the end zone. The other 3 at least are capable of big plays while Housh has yet to score this year. Marshall looked like he has gotten back into playing shape with last week's effort and has become Orton's favorite target. Walter didn't do much last week, but he didn't have to as the Texans got a nice lead and just ran the ball for most of the 2nd half. Boldin is your must-start out of the bunch now that he is also healthy. I would say Boldin, Marshall, and Walter.
