Will This Solve Johnson's Bowling Woes?

I think McGrath is wrong when he says that Johnson's wrist position is fine. To me, it looked like Johnson was cutting his fingers across the ball like a left-arm spinner rather than getting his wrist behind the line of the seam and attempting to swing it...the seam was coming out scrambled most times, so he didn't get any swing. He then tried to bowl too quickly to compensate and as a result lost his line and length too. The first part (wrist) is a technical problem, the second part (bowling too fast) is the resulting mental issue.
