I don’t recall any 4 WR sets vs. UNH, but I think the gameplan was possession and keeping the ball away from the UNH offense. And in the second half the playbook was closed.
One underrated aspect of the offense has been the overall lack of bad turnovers. They did turn it over against UNH but some (Knott’s injury, pass through receivers’ hands) not Shaf’s fault at all. I feel pretty confident that they will continue improvement. Its the D where we need to see much more.
