That's pretty much a good description of our offensive game plan...
Of course, every scheme is only as good as the talent running it. Because the offensive line is often blocking for a run without knowing whether the play will in fact be a run or pass, the throws in packaged plays are often short quick-hitters, good for no farther than a couple yards down the field. This is the second reason behind the newfound prominence of these plays — it's another way to get the ball to your best athletes in space. The NFL has seen an infusion of fleet-footed slot receivers and scatbacks — space players — and the entire point of the packaged play is to get these guys the ball whenever they have some extra room to roam.
Why do you think we've been loading up on big TE's and small quick WR's??
