Ponting isn't as out of form as people think he showed form in the second innings at the gabba he hit 50 off of about 40 balls. England set up Ponting and Clarke by bowling consistent line and length outside, Ponting has always struggled against such bowling early in his innings.
your 100% correct, england are good at this and Strauss was very good in his captiancy. The main thing is Ponting is normally very good at building an innings. In 2005 to 2007 when he was killing it, no matter what score he was on he was smart about his batting, never got over owed about milstones or anything. He just batted.
Now ponting looks over agressive, he loses concentration and is playing balls that he shouldnt be and getting out. I have seen ponting get hanging his bat outside off about 30 times in the last 3 years and edging it to the slips. If he isnt getting out that way he is running himself out. It shows me that he is becoming inpatient and lossing concentration which was always his greatest strength.
If he moves down to 4 or 5 and losses the captiancy maybe he would return to form. If Ponting and Clarke make 3 hundreds each in that ashes then We dont loss any test matches. Ponting is the greatest Australian batsmen since bradmen and deserves his spot (he was our best batsmen in India aswell) but clarke has not produced since moving to #4 and needs a good stint in Shield cricket to work through his issues.
