Bingo. I find it so weird that our coach has literally said this and people still seem to think the momentum is slowed down because of McCullough. Getting rolled onto their backs every tackle means the defensive line can set and move forward as quickly as they want as soon as the ball clears the ruck. If they can stand or get to their front and play the ball quickly then McCullough can move the ball before the opposition has moved forward at all. This is one thing Thaiday never got enough credit for in his final years. Sometimes it's better to just hit the ground and get a quick play the ball.
