That's been my inherent belief all along, that Daboll was more effective at extracting the potential out of the offensive playbook. The devil is in the details, you can just slap a playbook together with this route tree and that zone block scheme...but there are going to be ways to optimize the effectiveness of those plays. For example:
The receiver who is supposed to tie up Whitehead's attention long enough to get Diggs open on that post (Sherfield?)
Gabe running an unassuming flag route that gets jumped.
Late last season, there was a play where Dawson made a head fake which totally created the room necessary to fit the ball in on a TD.
My contention is that some of Daboll's keys are still remembered & run - Diggs is probably first and foremost. But with new receivers, if they aren't being shown those gritty details that turn a batted down ball (or in Monday night's cases all too often, an INT) into a tight-window completion, it's gonna be a whole lot tougher for this offense to succeed.
