Sorry I'm not buying this. You are suggesting that Johnson knows the exact CADENCE of Drew's huts. We're talking milliseconds here. Bledsoe delays or accelerates the time between huts based his own decision at the time (unless he calls for a quick snap and that would be on the first hut). If some lineman thinks he can go on a visual signal it would have to be something Drew does, HE determines when the ball is snapped.
I prefer to go with the conventional wisdom Bledsoe and Johnson are trying stay a millisecond longer to make sure the exchange is made cleanly. This should improve each week.
Tivo's great, but the smoke from the grassy knoll was a cigarette puff.
