1) Ryan Grant
Grant didn't light the world on fire in Week 1, but 60 yards and a touchdown out of your (likely) No. 2 back won't kill any fantasy team. Grant should find more running room in Week 2. The Bengals' run D isn't exactly the Bears' run D.
Cincinnati actually did a decent job against Broncos runners last week, holding them 75 yards on 20 rushes. But the Packers are very tough up front, and Ryan Grant is twice the runner Cornell Buckhalter will ever be. Same goes for Knowshon Moreno, at least in his first professional game.
100 yards and a touchdown seems like a safe bet for Grant.
2) Fred Jackson
Vs. Tampa Bay
Marion Barber and Felix Jones tore up the Bucs to the tune of five yards a carry in Week 1. While Fred Jackson isn't at the level of those guys yet, don't discount the fact that he's fighting for a job.
Jackson was solid in Week 1, with 57 yards rushing, 83 receiving and a touchdown. If he keeps playing well, he'll continue to get carries, even after Marshawn Lynch comes back.
In my main league, I'm going to start Jackson over Ray Rice. I think he's due for a big game against the Bucs.
