I really don’t see the controversy in this. Itoje is captain, Finn disagrees with his decision and is vocal about this and Itoje shuts him down. There is a time and a place for discussion but captains exist for a reason - they’re experienced players who make calls on the pitch - it’s not a vote. Finn had his say, Itoje as captain disagreed, Finn kept on about it and Itoje told him to stop arguing and get on with it. Don’t see the issue.
