People make too much of these "unofficial" depth charts. Even during the season, if you watch the actual rotation that tells you who is where on the depth chart. Hill at CB is simply because Rochell missed so much time last year. IMO by the break, it will be Rochell and Durant who are the #2 & 3 CBs IMO. Having Hill as a starting CB won't last. He proved here in LA and in Cleveland that he's a limited zone CB and nothing more.
I expect Hollins, Hardy, and Lewis to rotate during the season opposite Floyd. I do expect Hardy to be the primary backup to Floyd if he gets hurt or comes out for a breather. Hardy IMO will pass Garrett and Lewis on the rotation depth chart at the edge opposite Floyd coming out of their bye week.
I expect Williams to be the #3 RB for the majority of the season. I think coming out of their bye week, Williams will take up the role played by Michel last year in terms of being their 3rd down RB. He's been slowed this TC by getting hurt.
Week one and two of the regular season will tell you who is where on the actual depth chart.
