If you’re interested, Virginia’s former director of analytics has done a deep dive into what’s behind explosive pass plays. (It is a subject for which he can claim some degree of expertise, based on last season’s statistics.)
What’s cool for me is that factors he examines — “reduced” formations, pre-snap motion, play action, for example — are all part of Monken’s offensive scheme. There’s some good analysis there, so give it a read.
