Most Definitely Housh. Big Ben just doesn't seem like himself yet and they are a run first offense. Housh has one of the best QBs in the league throwing to him and is one of Palmer's favorite red zone targets. I think Housh will get more looks in the end zone and Cincy will be getting there more often than Pitt.
Based on those projections alone, I feel Housh is the more valuable reciever in the long run.
