I think a top 5 rushing attack could be in the cards. Tops in the NFL, I don't see it. We'd have to pick up 70+ yards per game against the Ravens. Add in the passes to RB's (Hines) in the backfield and I think we'll see something like 150 rushing yards per game and 230 yards passing. That would be a great offense.
I think both have a good chance to break 1,000 total yards from scimmage, but not sure about rushing yards. I know neither back has been known for receiving, but with Rivers, I think they both end up with more catches than most are expecting.
