(LOL!) What Happened To All The Empty-Set Formations?

Not saying that they've been completely ripped out of McStafford's playbook, but it sure has been nice to see the return of all the motion on offense the past few games. Have to assume that a lot of this has to do with: A) the emergence of Robinson as the 3rd WR; and, B ) Higbee's return to (relative) health?

Though our OL/RB is much-improved, I've no doubt that the eye-candy is buying them the fraction of a second needed to get to/read their blocks.

Though he got blown up on his end-around, LB's and Edges will have to honor Kupp (and/or Puka) on those jet-sweeps.
