Batting for two days means scoring 600. Unfortunately it has been 20 innings since England scored more than 400 in an innings. I think their chance of such a turnaround on a pitch where they have historically performed so badly on in the past is somewhat unlikely.
Looking at the weather radar, most of the heavy morning rain has already passed through. There is still a little bit of lighter stuff that might be about one hour away, but I wouldn't be surprised if it starts on time.
Are these umpires even bothering to look for no balls themselves? They're asking for referrals after every single wicket. On the last one Siddle's whole foot was almost entirely behind the line.
Admittedly, there are some light showers forecast in the next couple of days, but you do realise that Adelaide is the driest capital city in Australia don't you?
I'd call bowling consistently at over 93 mph 'genuine pace bowling'. And given that 5 of his 7 wickets were either bowled or lbw, I would suggest that he was bowling with pace and accuracy.
