On the other hand, if they find evidence that he changed his behaviour, the suspension should be lifted immediately and he should be allowed to rejoin the squad asap.
Michael Holding, Michael Vaughan etc share similar views. No matter what the verdict is, his reputation definitely took a big blow.
One decade old tweet is not a valid reason to ban a player. The ECB seems to be in a desperate attempt to show off their political correctness. I don't think that they would have taken the same approach, if the player was Muslim or Black. If Ollie Robinson had exhibited any such behavior during the recent times, then I would have supported disciplinary action against him. But they are digging up his history and trying to find a reason to destroy his career. And now everything has got political, with the left-wing Labor party supporting the ECB move and the governing Conservatives opposing it.
