The author needs help to understand the rule as he showed a play where Reek is in the backfield. The new rule doesn’t impact him since he’s not on the line of scrimmage.
This will however prevent a wr, on the line of scrimmage as eligible, to motion into a jet sweep handoff. If I were McVay I’d line all 3 WRs on the scrimmage line and then back 1 off (would need at least another wr on the same side) have him set, and motion him in the backfield and approach the QB to either fake a sweep, block on run plays, or take a hand off.
Sham-a-man will definitely copy, but this play design exploits the loophole in the play change.
FYI, I’m still uncertain why the new rule results in a false start and a dead ball. If it’s flagged ans illegal motion or shift, that’s a live ball foul. The difference is the illegal shift or motion is correctable prior to the snap, while a false start feigns a snap has occurred. My $0.02.
