I think in comparing other recent teams which toured Ind versus current Aus (and thus predicting the 4-0 whitewashes on Aus), most folks under estimated/ignored the quality of the aussie pace attack in addition to the extensive spin preparations of the Aussie batsmen. Despite SOK's outstanding performance, I think the flood gates were really opened by the superb bowling of hazlewood and starc when they accounted for all three Test inform batsmen vijay, pujara and kohli..
Lyon and SOK performance was really a bonus performance showing that if India go about preparing spin surfaces, they also have to handle these two with quite a bit of difficulty ...And despite Indians being great players of spin, in reality the major difference between visiting teams and indian teams is in the indian spin bowling quality more than the ability of the batsmen to handle spin...I am sure if India and Eng played with Ashwin and Jadeja playing for Eng and moeen and rashid playing for india rest all being same, the results would have been quite different...Ashwin and Jadeja would run through the Indian lineup equally easily on those rank turners..
