I think he meant he gives a dummy count to see if the defense adjusts when they think the ball is being snapped. If they do, he adjusts protection again before calling for the ball for real.
No, No.
He said he gave a "ringo" or "lucky" call after the ball is snapped to "re-direct" his offensive line if he gets unexpected pressure.
The offense I played in, in college was pretty sophisticated...but we didn't have any post snap calls...None...
The way TB explains it, he would make that call almost as soon as the ball was snapped. After he took his first step which is his "read" step. If he sees the safeties rotating, coming down..He knows that he might be getting pressure from that side so he makes the call if he has time.
Seems like a pretty watered down explanation overall, but you can tell he knows his stuff.
