Wow! That's some great advice from "high-level" rankers. Thanks for the input! Unfortunately, it's also advice with no clear consensus.
It's almost impossible to predict what's going to happen. They are all pretty much in the same tier. I put KJ last because of consistency. I benched him after his 10 carry, 8 yard, concussed performance and then he goes for 120+ and a TD.
I put Tatum first because he has some great matchups...including Cleveland, Indy, Oakland, Arizona...plus, I feel he'll be the most consistent performer. He does have Pitt and SDx2 though. However, Tatum did have a solid game against Balt's vaunted run D.
Chester has some very nice matchups as well...SF, GBx2, Arizona, and NYJ. He's also inconsistent though.
I think Gore has the worst of the matchups. He has a lot of tough ones ahead: @Chi, Min, @Det, Sea, @StL, and @NO. The only teams ranked in the bottom half are StL and NO...and Gore will be playing on the road.
In case you hadn't noticed, consistency is very important to me when ranking players. All of these players are pretty unproven (Gore, Chester, and Tatum are all in their first year as starters), so there isn't much data to use.
