Ocho for sure, he's the team's #1 receiving weapon for the most part. And he's playing against Cleveland.
I liked what I saw in Marshall last week (blast @ myself for trading him a couple weeks back). Ultimately for me, the decision would rest on what the rest of my team is looking like in my match-up this week...
If I needed a potential break out player (i.e., I was projected to lose by a decent amount), I'd definitely go Marshall. If instead I just needed a solid couple of points, I'd probably go with Manningham.
