Do you mean O-line, skill players, or just in general?
To this untrained eye, it looks as if they've diversified what the O is capable of offering each week by strengthening the passing attack in the backfield and TE positions, adding Cook and Howard. WR has a slight difference in the strengths that Crowder and Beasley offer, but, other than that, it's kind of a wash (possibly better with Davis getting more snaps?). No real upgrades/changes at OL, so wondering if that's what you mean?
