I'll give you the defense part. As far as that goes, Kingsbury isn't going to coach the defense. A DC with experience will be hired to completely run that side of the ball. So that's a non-issue here.
As to the running the football part, if you think the trends of offense haven't shifted from passing to open the run vs old school run to open the pass, then you have been in a cave the past five + seasons. The game on offense has absolutely changed to a more wide open game. The rule changes have contributed to that. Is a solid run game still important? Sure. But not as important as it used to be.
I heard today on the radio that while at Texas Tech, Kingsbury only passed the ball 55% of the time. Not sure if that was his entire tenure or just last season. If true, a 55/45 pass to run ration this day and age is very reasonable. But that was in college. He will adapt his offensive principles to best fit the NFL game. He's no dummy.
