I've heard this before and it's fairly common with offensive minded, passing oriented coaches. They like to get the QB throwing a short pass on the 1st play of the drive to get the QB into a rhythm.
The problem is that they usually end up throwing the ball too often in hopes of getting the QB into a rhythm and I think the entire rhythm thing is overblown.
It doesn't equate to the same thing as a 'running back needing to get into a rhythm' because the QB on a low amount of passes in a game is still throwing the ball about 30 times a game. When a RB can't get into a rhythm, it's usually because they are only getting 4 or 5 run attempts before getting yanked.
This has me concerned because it tells me that at the first hint of trouble with the running game that we will abandon the run and start throwing again.
Garrett could really take some cues from Tom Osborne as to how to manage a game and the offensive playcalling. Despite being a wishbone, heavy run oriented offense, Osborne knew how deal with certain plays that were not working or when the running game as a whole was getting stifled.
One of my favorite games was against the U. of Miami in Warren Sapp's senior year (I remember this game vividly because I bet a week's paycheck against my friend that Nebraska would win).
Throughout the game Nebraska would hand the ball to the fullback and only gain 1, maybe 2-yards. And they would do it on 1st and 2nd down.
I couldn't understand why Osborne insisted on running that play because it wasn't working and the only time they could gain yards was running to the outside or faking the run and throwing.
And still into the 2nd half, Osborne would keep using the FB run and only get 1-2 yards.
Eventually the FB in the 4th quarter started to pop off a 4-yard carry, then a 8-yard carry. But then back down to a play where he got stuffed. Eventually on a critical play late in the 4th quarter, they handed it to the fullback and the defense wasn't prepared for it and the fullback had a 20-yard carry for a TD to seal the game.
And it dawned on me the greatness of Osborne's playcalling. Not every play is going to gain significant yards. So he used the play with little likelihood of gaining big yards to keep the defense honest and to set up the perimeter runs and the passes. And when Miami gambled too much on the perimeter runs...that FB run was right there for the taking.
Unfortunately, it seems like Garrett wants to throw the ball because he feels they'll likely gain more yards than if they run. But, there is nothing there to keep the defense honest in any capacity and for all the worry and concern about getting Romo in a rhythm, it doesn't make Romo's job easier.
