When bumrah made his test debut (2018)at Capetown i clearly remember Ramiz raja, Micheal Holding and Mike Hayesman were commentating and when one of them asked holding about what's your opinion on bumrah the test bowler and his future. Holding I think said he will be effective but he was not sure whether his bowling action will allow him to play more than 25 test matches.
What a coincidence he played his 25th match at Centurion and took his 100th wicket but Micheal Holding retired from commentary box.
