I'd go with Mixon. He won't be going against the Ravens front every week, and I gotta think the Bengals may try to run it a bit more often seeing how bad Dalton looked.
I'd probably roll with either Cohen or K.Williams over any of those guys in Week 2 if you can either of them up. If it's a PPR league, then Cohen is clearly the best of the bunch.
Cohen is already owned and I'm sure Williams will go before my waiver claim of 10/12. Actually had him earlier last week but I dropped him to add Raiders DST.
Aiming to get Tolbert and Austin Hooper. I have Matt Ryan, so the double dip might be nice.
Allen Hurns might be a good get too, but I have solid WR's as is.
