Does it look
Something like a pitcher finishing with a walkthrough?
( but more explosive)
Or
After they finish they sort of leap/step and round off squaring to the batter?
Their not squaring to the batter, it’s another jump.
As far as I know only one of their PC’s are teaching it to half dozen HS age pitchers.
Umpires say it’s legal as long as ball is released at first plant.
I’ve seen three pitchers from that class so far.
