It's really not a sexy play, and rarely worked for big gains (we got 10+ yards on 18 of 90 attempts). But the play isn't designed to pop for big yardage, it's designed to set up other plays. It forces a defense to cover the field sideline-to-sideline, and if they don't, and if our perimeter blocking is good, and if our QB gets the ball out there in good time, it's a positive-yardage play.
Our biggest problem with this play, and the reason the fans hate it, is that our perimeter blocking is often terrible, the passes are often errant, or the timing is off. That results in no gain or negative-yardage plays, which happened 40 of the 90 times we ran it.
UCF ran this play under Frost with much better success than we do. But they had better athletes on the perimeter, and (to date) we don't have a McKenzie Milton in the QB room to put the ball on target on time every time.
For Nebraska, it was feast or famine with this thing. Half our games (N. Illinois, Ohio State, Minnesota, Purdue, Maryland, Iowa) we averaged three yards or less with this play. For the other half (S. Alabama, Colorado, Illinois, Northwestern, Indiana, Wisconsin) we averaged seven or more yards with this play.
Weird thing is, success with this play (and thus, spreading out the defense) didn't matter much to wins or losses. In our six games where we were less successful with this play we went 2-4, and in the games where we were more successful we went 3-3.
After watching it just one time the paragraph I bolded is my conclusion also. Perimeter blocking was terrible on most of the negative or short yardage plays or the pass was behind the receiver or off target or both. I will add one more thing. When the RB goes in motion right before the snap and leaves an empty backfield it is really telegraphing what they are doing. I mean they know where the ball is going in that situation. When you combine that with poor blocking and a poor pass it can lead to disaster.
I will also add that the flat pass/screen/swing pass is one of the hardest things to throw accurately with a lot of consistency. To hit someone in stride when they are running down hill is tough.
