One of the cool things with RPO plays is it gives the QB opportunities to throw against single coverage with the defense often thinking it's a run. All it takes is a bad angle or a missed tackle from a cornerback and a simple 12 yard slant might pop for 20+ yards.
We need more diversity and better, quicker adjustments from the coaches. The receivers need to run crisper routes in order to get open quicker with better separation. The OL has to play better as a whole, starters and reserves when needed. And as
@TwoDeep3 posted, Dak Prescott must address his accuracy issues.
Putting a pass on a wideout's back shoulder with a trailing defender when it should be in front of him can be the difference in a chunk play for us or an interception/pass defensed for them.
There's so many things involved.
Dak has been pretty conservative so far in the NFL and he needs to take more deep shots to help loosen up defenses. But he also has to learn how to take those shots with different receivers running the routes. Dez likes to stop, jump and high point a lot of his deep balls whereas Terrance Williams prefers to run under it.
