Most uneducated ever - I wouldn't go that far. Certainly Clarke had a lean patch in the middle order until recently, but to say that he can't hack opening the batting is a bit stiff. He hasn't yet been given a chance, not because he can't (IMO), but because of the plethora of good openers we already have. If Langer/Hayden were injured, Jaques/Rogers would get first crack. We don't need to promote a middle order player. If we did it would be Hussey.
Traditionally, you don't want your best players to open anyway. Prime example of Kevin Pietersen. He bats at 5 (4 when he's forced to), to give him a chance to smash the old ball around with less chance of seaming and swinging. That means reducing the risk of your best player getting a ball that could have been avoided if he had waited 15 overs before coming in.
Clarke shouldn't open for NSW either, he should let less valuable guys go in first to blunt the bowling.
Virender Sehwag is a prime example of a guy who started in the middle, but the middle order was too crowded so he was promoted to open. He has bad off stump technique, yet he somehow manages to score runs opening the batting, go figure. He would have been a guy I would have thought would be eaten alive as an opener, yet he averages around 53 as an opener. Michael Clarke would be the same IMO. He plays very much like Michael Slater - not a bad opener coincedentally.
