Timing and rhythm. I'm giving the running game a little more patience. When you're running a zone-heavy scheme, especially this Alex Gibbs-style stretch/outside zone offense, it's all about timing and the OL getting enough reps together. The backs getting a feel for it and learning to read the wash up front. Every run can hit at potentially 3 different landmarks. It's not like lining up and running gap-scheme power and counter, where it's down block/deuce block, pull/kickout, etc., and you basically know exactly where your crease is gonna be. There's a lot more moving parts.
