However they send in the original play call by Frost (or hopefully Whipple this fall - at least it may be some new sequencing and so on), the key is to get all 11 to execute their assignments well. It’s hard to know from just watching who is and is not running the plays correctly, especially in the passing game where QB and WRs and backs / TEs are presumably ‘ad libing’ on the fly. Presumably, Frost offense has plenty of QB-Rec reading and adjusting post snap based on the defensive reactions etc. This can lead to the feast & famine kind of offensive output we’ve seen.
I believe the idea for signaling in plays after lining up is to keep the defense from making substitutions and to allow Frost to ‘read’ the defense instead of the players on the field. I suspect most of the QB ‘reads’ are post snap, especially on the 50% of plays (my estimate) with RPO aspects.
My hunch is Frost is pretty good at creating and designing plays to attack defenses in their weaknesses. But players - too young, immature, inexperienced - are just not ready to follow thru in the schematics at split second times. Too much thinking. Too many reads by too many guys. Just too complicated - maybe.
Osborne had a very intelligent, complex offense but very rarely did he rely on first/second year guys. Blocking was very complicated too. Development and learning was critical. Recruits expected to redshirt, play scout team, grow, learn and practice BEFORE seeing game snaps that mattered. I’m not sure Frost & Co have told players this ‘reality’ in their quest for star recruits. Thus, execution / consistency have failed to produce sustained drives and points.
