I'm one of Dak's bigger critics and I say no we haven't (this season at least). You can't win it all with no rungame in place. Simple as that.
But no offense is perfect. You can't have it all. Dak will have to work with he's got. So I say don't invest too much into a great RB but fix that o line. It has more holes than a swiss cheese. You need new personell and a new O line coach. Even mediocre RBs (and QBs
) will look good with a great o line. So work on that, everything else will fall into play.
