It's funny how you see the Konstas dismissal. At first, I thought the ball was probably missing leg and should have received any benefit of the doubt. I watched the replay three times after that, and I'm still not sure. The ball seemed to straighten and may have struck the back leg. If that's how the umpire saw it, then out. However, there just seemed to be sufficient doubt for the umpire to give it not out. Would need better equipment to know for sure.
First replay looked sliding, subsequent replays show the leg coming across and not as bad as first seemed. A lot of foot movement from the greatest batsman since Bradman but the umpire would have seen him in front of middle and leg and hitting back leg.
Even a review wouldn’t have saved him.
