It's not possible for human to check all 600 balls for no ball.this happened in earlier too.lot of mistakes from umpire side corrected with technology now.we can't check all 600 balls using 3rd umpireI have found very good quote on yesterday match:
#credit twitter guy.
Universe boss Chris Gayle could have single handedly taken game away in Aus vsWi if it was given No-Ball by Emirates Umpire. As I said during Vivo IPL, its time fr umpires to wear Crizal powered Lenskart framed glasses and have Syska LEDs in floodlight for clear view. #WIvAUS
Gayle got hit on the pad 2 times in the same over which shows he is old, unable to judge the ball.
Even if he's escaped in that ball he would have got out by giving a catch.west indies players still in t20 mode and can't even win a easy match.
If Gayle's out then what other players did especially Russel and brathwait.no sense of mind attacked Mitchell starc unnecessary and got out.
