I think you and
@ThreatMatrix answered this in following posts! Really, you've got to have a run game that you can call upon for a variety of reasons. No.1 for me would be that the D only has one leg of the offense to concern themselves if we can't/don't run it. They sit in 2 Deep Man/Under or Man/Free and rush with four or five. For a great deal of the second half, they only rushed four and our five OL guys had a heckuva time blocking them (e.g. our C got pushed on top of the QB about the time the snap got to him on a few occasions - this scenario also allowed a LB to jam or hold :) Pitts and disrupt his routes some, part of why he seemed to vanish in the second half). No. 2, the ability to run the ball on your opponent can be viewed as a show of superior strength and fortitude. TD passes hurt, but nowhere near as much as having the ball surgically extracted from your hind parts after the opponent has shoved it up there over and over. Establishing this part is a mental edge that can certainly be critical. Also, most runs are designed to get the backs into space with a head of steam and in a match up with a DB. No.3, when you need a yard (or six inches), you've got to be able to get a push to get it. Nothing pops a balloon like getting stuffed in these situations.
A lot of the preceding sounds like old school football thinking, and I guess maybe it is, but in spite of the emphasis on the passing part of offensive football, there'll always be a need for the run and therefore some balance. Maybe not 50/50 (though you'd be surprised how close it is in many games), but you can't get away from it, even if your OL is not good at it ;). While we're on the subject, I watched Mullen's Monday presser and he said something to the effect we rushed it a little better than we had. Didn't say he was satisfied by any means. Stats say we rushed 40 times for 146 and a 3.7 average per carry. It may be slightly better, but it's still just enough to get you beat! I'm not sure we (the fans) didn't fool ourselves into thinking that we were good enough to beat good teams without being able to run it. Until we can show otherwise, the better teams will find us easier to prepare for than one might think given our passing attack with a good QB and a great stable of receivers.
