Mike, I would bet my game check that this would be a case where we have a flag down for an IBW, but with good communication with the H, it would be picked up, as it should be. When the ball is snapped, the motion man is not yet to the ball, so his adjacent sideline is the one to his back, which is the direction of is low block at the end of the play. This is why we are going to have to know the numbers of our current, and initial keys better than ever this year.
For us deep 3, we are going to have to stay with our keys much longer as the BBW we saw last year 15-20 yards downfield towards the center, on a run to the other side that were legal last year, will be illegal this year. I saw many examples of this on video at our clinic this year.
