You could spin it round and ask why, if he didn't have it under control, did Root start walking off immediately?
Because he thought I was caught, before Yadav cocked it up? Not sure what Root's reaction has to do with it anyway tbh. On-field umpires bottled it and stitched the third umpire up by giving a soft signal if you ask me, slomo was never going to find a reason to overturn a decision either way. Those are given no 99% of the time.
Kohli isn't even on the same planet as Williamson in tests, sorry!
