International 12th Man
His contemporaries were already in decline at his age, and his contemporaries have a different playstyle than him, Root has done well in India and well his record isn't great in Aus but you can't win them all, on the contrary the next series is a pakistan series, then a newzealand series where Root does very well, a one off with Zimbabwe followed by a 5 match series against India at home, if anything his next 15 or so test there are much higher chances of him boosting his average a couple points than it falling for example.That he did well in the recent past is still no guarantee of future success. I mean we've seen in series vs India in India or Australia in Australia that he's had the occasional big score before 'disappearing' and this isn't exactly the era where every pitch in the world is a highway, making batting easier. I understand being hopeful and wanting well, but it's silly to pretend people are wasting time by assuming a downturn in form towards the end of Root's career, when we've literally seen that with his contemporaries at points.
and Yes, Assuming there would be a downturn is indeed a waste of time, because until you're Yhwach from Bleach you can't see the future, he might miserably fail in pakistan or he might average 100, the fact he has shown no signs of decline at 33 should just tell you that "decline based on age" isn't a guaranteed and everything from here is speculative.
